Subject: Tech: Computer backup - Win10, UPS, external H
From: Acme
Date: 04 Apr 17 - 08:46 PM

Time again to consider how I am backing up my computer. I currently have an external hard drive where I do a periodic full backup, but I'd really rather have an incremental backup every day or two. I put the external drive out of sight in the off chance that the house is ever burgled again and I have at least that to fall back on.

I have two UPS (Uninterrupted Power Supplies), one for the computer and monitors, and one for the router and modem that live on the top shelf in the hall closet. Out of sight, out of mind. Probably out of view of any burglars.

My house is networked (wired), the computers and the BluRay players all talk to each other, as does my phone. Has anyone put an external hard drive with a UPS and router (plus I have a switch in the closet because there are data ports in most rooms of the house) and backed up computers through the network? I imagine it would take longer that way, but once the initial backup is in place, the incremental ones would be a snap (last full backup when the current external drive was new took a couple of days - I backed up everything.)

My computer has two internal HDD drives, both very large, and a modest sized SSD drive with just the operating system on it. I have an external drive at my desk also plugged into the computer (a now-seven-year-old HP quad core running Win 10).

I tend to leave the computer on much of the time, with it set to go into sleep mode after a couple of hours of inactivity.

I need to pull out the instructions for the UPS in the closet, though that one doesn't talk to the computer like the one in the office itself does. I can run a data line from my office computer, through the wall and attic and down to that other UPS, but it might be confusing to have two connected. My network is through the router and switch.

Does this provide enough information? One of these days I will get a new desktop and plug all of this stuff into it (printer, scanner, USB hub for frequently used cables - phone, camera, mp3, extra mouse and extra keyboard). I have a Canopus card plugged in for converting VHS to digital, and the computer is in the proximity of a stereo system to run cassettes or LPs into it for capture.

Every so often I go through an upgrade, when the computer capacity is a problem or the OS changes, but for now it's okay. Win10 Ultimate is up and running. But that backup - something it's too easy to overlook but important for so many reasons.

Thoughts?

It seems to me that you have as well thought out a system as almost anyone I know. I actually gave up on using a UPS several years ago, and my backups are now just the things most important to me..... my GEDCOM files, my music/video files and my copies of my program installation files..(portable/zip whenever possible). I have several large capacity portable HDS and several good USB thumb drives.

It never dawned on me that one COULD connect a UPS with an external drive, but these days almost anything you can think of has been implemented.

The ONLY thing I'd even offer to someone that careful is a list of incremental backup programs. I use Cobian Backup myself, but it is no longer under development, and I have seen others suggested in the alt.comp.freeware newsgroup.

I have a number of external hard drives and a Network Attached Storage device with two hard drives. I do manual backups on occasion, but haven't found an incremental backup software program that I like.

I installed Carbonite at the women's center where I used to work, and I was very pleased with it. It's only $60 a year for unlimited storage for one computer, and you can access your data anywhere.

One of the staff members insisted I had installed the program incorrectly, and she changed the Carbonite settings on all our computers (without consulting me) and texted me to say that she and the board of directors wanted to know why I did not have the backup set up properly. It was indeed working properly. But that's why I quit my IT volunteer job at the women's center after 18 years.

The employee got a virus, and then backed up her infected computer to Carbonite. Nonetheless, Carbonite technicians were able to restore older versions of her data files. And she had the nerve to complain about the files being a week or two old (after she had infected the most recent backup.

But Carbonite worked properly, despite concerted efforts by an idiot to screw it up.

A few thoughts:

The best feature I found in Win 10, having upgraded my wife's laptop from Win 7, is its File History incremental backup. She backs up to a 'passport' USB3 drive.

The obvious network backup device is a 'home NAS' box. My son has one made by QNAP. It's a RAID device, so supposedly less subject to data loss than an individual HD, though I would mistrust cheap ones. He stores masses a stuff, including music, on it.

You can also hang drives on a router. I fancied a Turris OSS router a while ago but it was too expensive. But cheap routers are increasingly vulnerable to outside attack, and my new Netgear router is not great in that respect, so I may still get one.

The main complication, IMO, is mitigating the threat posed by ramsomware. Some of that will encrypt every connected drive, including networked drives (or networked shares). For that reason my wife's USB drive is not kept plugged in, which makes the process non-automatic. If you're backing up to a permanently network-connected device you need to investigate how to protect it. I don't know how NAS boxes do that, but if I were buying one I'd certainly want to. And I wouldn't trust anti-malware software alone to do it. One reason I liked the Turris+HD setup was that it would be very unusual, unlikely to be targeted by malware writers, and patchable long-term (unlike Netgear).

I do incremental backups over a wired network connection, but using Linux. It's pretty quick (I use rsync). I considered backing the Win 10 boxes (I have one too) to the same drives but the problem I hit was that my Linux drives are all accessed via NFS and you need Windows 10 Enterprise (IIRC) to use them - which is expensive. I don't know how NAS boxes do it - maybe they include NFS drivers.

Hope some if that helps.

DaveRo, that ransomware threat is a consideration, part of the reason why I thought about putting the backup on the network and not directly on the main desktop. It might be something I'll have to leave in place but disconnect until I want to do an incremental backup. There is an internal backup that is incremental, something that Windows will do and I set up, but that's helpful only to a point.

Norton Ghost stopped being produced several years ago. That's what I used previously. Win10 doesn't support it, though Win7 did. I guess Symantec decided Windows had the backup needs covered.

Before the upgrade to Win 10 we used the built-in 'Win 7 backup', which is a non-incremental selective backup. We backed it up to my 'music and backup server' - which was effectively a NAS but was actually a 10-year old Linux desktop. Win 7 backed up to a shared drive. It worked OK; my wife or I ran the backup periodically. We just had to make sure the server was turned on. (Win 7 backup is in Win 10 too btw, but hidden.)

When ransomeware appeared I decided this was too risky. I put a password on the share, and told Win not to remember it or reconnect automatically. To run the backup we had to 'connect network drive', and type in a username and password. This worked - but not well. It often took several attempts to connect and I thought it possible that ransomeware would connect it anyway, that Win would actually store the password somewhere.

With Win 10 I got rid of these Windows shares, both backup and music, as being too vulnerable. For backup I changed to an unpluggable USB drive - much simpler and proof against malware. (Unless the malware sits in wait until it's plugged in...)

So if you want to use a network-connected backup drive and don't want to keep unplugging it, you could try a password. It might work better with an all-windows setup, for example between two Win PCs.

NAS-makers must have thought about ransomeware, I wonder what they do? I bet ransomware-makers have thought about NAS!

As for UPS I've never had one. I see that some NAS boxes can connect to UPS via usb to initiate orderly shutdown. It shouldn't matter if the NAS has RAID and a journalling file system, I would have thought, but I don't really know.

Dave, re your NFS question: I don't know specifics about any off the shelf NAS boxes but I wouldn't be surprised if a few use *nix as the underlying OS.

I'm just lousy at backing up and know I ought to improve one day... rsync would be my likely route. .

Yes, NAS boxes all run a customised version of Linux. But I assume they normally install software in Windows to handle file access. I expect it'll look like Dropbox's Windows software which handles cloud file access. It might use NFS, which isn't supported in Win 10 Pro, or SMB which is. Win 10 Enterprise, which you need to use NFS, costs $7/month, I think.

NAS boxes are easy to set up and use - to play music, store photos, etc. The question for me is - how do they make it easy to use while making it hard for ransomeware to access? And which of those two objectives will the vendor prioritize? Which will make it sell?

On Linux I used to use BackInTime - which is a UI for rsync. These days I just use rsync in a script; the options are legion but once you get it working it's fine, and super-fast. I wouldn't be surprised if NAS boxes use rsync underneath - in which case they need NFS.

Yes, I've used Samba (SMB file access) for years. I used it for Win XP then Win 7 backup - including the password system I described - and I could use it in Win 10 if I had to. But because of the risk of ransomeware - which can encrypt Windows shares - I don't want any permanent Windows shares. (Or not writable ones.)

Yep it's easier to preach to others Joe..

That said, sad as it may sound, I'm not sure that I have a lot that needs backing up. Some photos for sure but it at least feels a while since I've invested a lot of time in something which in my case could include (OK redundant but) folkinfo code or an Android->Cups printing program I still use. (which as are backed up backed up on DVDs somewhere..)

Probably ought to be more responsible for my parents usage.. I think I do a reasonable job in ensuring they have a pretty stable platform (which reminds me dad is in hospital at the moment and I need to sort his wifi on the laptop out tomorrow - it was PAT tested today ) but plans for backing up often get deferred....

I'm now considering the possibility of simply putting the external hard drive in a totally out-of-sight place but not on the router or switch. I had thought perhaps a long data wire, but the drive and computer require USB, not data plugs. I suspect a very long USB cable would have it's problems (akin to serial vs parallel for printers -
too long isn't a good idea - running it up through the wall, across the attic floor, and down into the hall closet where the router and second UPS lives). But I could simply run it through the wall into the next room and place this in an inconspicuous spot that is physically only about five feet from the computer. Power and USB can both go through a junction box in the wall that is adjacent to the junction box in the next room. And I'd be able to plug it in to the nearby UPS and unplug the USB so it would only be in use during incremental backup, then disconnected from the system.

Most of "my stuff" is BS stuff. However, the really important stuff is loaded, saved to flash, and has the original. Carbonite is for work.

Once I have a "stable home platform" I will not permit "updates" to a my system. Every "crash" I had in the past came immediately after an "authorized patch."

A friend who is in the PC repair and set up business has a VPN located on a network drive, permanently connected to the internet. I assume it is on the same UPS as his modem.

He then uses an encrypted connection (VPN) to it to access his files, emails, and the internet via a browser on it, while away from home & maybe the same internally. He says it is far more secure than any other way to access on phone or tablet (via apps). Being a common interface he only has to remember one system.

My solution to critical files like databases for my various websites is to use the webspace I pay for (unlimited). If anyone wants to dig & access the data it is already there in a far more readable format. They are welcome to my back-end software. If the are clever enough to find it they will still struggle with my spaghetti code.

Not only were his main files encrypted but ALSO all of his backups on the connected drives - these included scripts for his books and irreplaceable family photos. He lost the lot.

And dont forget that a few years ago soome idiot scammer sent a ransomeware virus around that had a bug in the code. This meant that encrypted files couldn't be decrypted at all. There's no honour amongst thieves.

FWIW
1) I have 2 laptops and 2 tower PCs.
2) Only one is on the internet.
3) The back-up HDD is not permanently connected. Neither is the internet. They used to say any PC could be found in an hour. If connected!
4) Some browsers (and favoured apps) with associated passwords are portable versions on a second HDD, with copies on the back-up and also on a memory stick I can use on other machines.
5) favourites with hints to those passwords, email (etc) are in a local HTML file that is my browser's homepage.
6) And with 8 domains I can make a new e-mail address for any registration that is inconsequential or is untried. Simple redirects to my covert address (same on website forms' email addresses).
7) I have certain browsers for certain websites. eg Flash movies (BBC iPlayer etc) on one, another (sans Flash) for general purpose, Chrome for translated pages, & Goggle Earth. There even is a browser from my AV company which purports to be secure and it is picky with websites.
8) Most scam e-mails come in to those disposable e-mail addresses, makes it easier to spot.
9) all this doesn't guarantee protection but it makes it hard for them, and there are so many easier targets. But I stay alert, after all - if this is a game I intend to win. I have a lot to loose.
10) the hard work has paid-off over the last 17 years - so far.
11) I am more likely to loose/corrupt things with finger trouble &/or brain fade. Now why the hell didn't I copy this text to clipboard before the BT (notso) HotSpot disconnected itself?

The article Why Windows must die. For the third time answers a lot of questions about operating systems and security.

I have a local file that is my browsers' homepage also, though I got tired of moving it around to different machines after every tweak, so I host it now via the small amount of space web hosting space my IP made available (I'm grandfathered in, new customers don't get this space). FileZilla quick connect lets me upload my updates easily.

This week was certainly convincing as far as keeping the backup drive disconnected when the backup isn't being updated. I also have different browsers used for different tasks, and I will reconsider using the annoying new Microsoft Edge. Since I have my own homepage as home in that browser, all I needed to do was add a conspicuous link to Google (since Microsoft will only allow Bing to be the default search on that browser).

First test of the new 8TB external drive for backup. It'll take a while because I don't have any USB 3 ports and I have tons of material. I'm not backing up the old incremental backups - they'll stay in place for now, but I'll remove a couple of the older ones if this works as planned. Redundancy is always helpful and memory is cheap. I'll have to remember to plug this new drive in on the appropriate day of the week so incremental backups can take place.

The new drive is stashed behind a stack of VHS players for converting tapes to digital. Those would probably be left behind by a burglar in a hurry, and I have a recent backup on a different external drive that I will keep in another room.

Previous backups have taken forever, possibly because of how I set them up. This time I let Windows pick all of my libraries (I've added to the typical four that Windows comes with) and not the libraries plus checking ever box for each disk. I suspect that parked duplicated data in the backup.

I also should turn off my computer more often instead of just setting it to sleep.

A word of caution
all forms of storage - floppies (remember them) HDD, SSD, memory sticks have an MTBF - someone (of this parish) who used external HDDs found out of 10 identical rotating disc HDDs, 2 had failed in some way in 5 years. & they were being used as long term storage not regularly.

I myself had to reload Firefox recently because of what I would assume was a soft error on a rotating HDD. Who knows why, vibration, gamma hits, or even wear.

SSDs are a system on their own. The internal microprocessor is monitoring the threshold of cells and when it gets close to failure swaps out a whole block and calls up reserve memory in its place. Maybe your better memory sticks do it. But as the prime HDD in your system it would get a lot of use - which affects those thresholds.

Interesting that this evening when I spoke to my son he was in the middle of moving his existing computer contents into a larger case (with a new motherboard and CPU). It's a small world.

FWIW - apparently
The current virus had a back-door for the instigator to release the block. The release was as simple as having a domain that existed. It didn't.
The investigator who found this bought the domain and it worked! he said he was a grown man jumping and leaping like a child as soon as he found it had succeeded.

I have not seen much about the mop-up situation - particularly in the UK Health Service, nor how devastating (after Sunday).

A bit OT but I put added a 3TB drive to my "general purpose server/ mythtv frontend" in the living the other day. Main reason is to store pictures from IP cams. It may be a bit ott but dad thinks that 9 token coins disappeared from his collection over the 60 days he was in hospital and there are quite a few people (eg. a carer for an hr each day) that can be around the house these days. I'm not going to back up but hope to be able to look back at recordings should another "disappearance" be suspected.

I'm running the multi platform xeoma btw and am pretty pleased with it. My more natural choice would have been ZoneMinder but I struggled with it's resource usage (seems to be a common problem and one Iv'e also seen levelled at the Windows only Blue Iris - with ZoneMinder, I believe it's often sortable if you have the time and patience) in a past play and have for this opted for a pay for solution for the current 4 cameras.

It's possible to purchase a multi-camera security system with a several Tb hard drive supporting them for a few hundred dollars. I've considered it myself. My next door neighbor put in a fake camera over her front door (it has a blinking red light and looks quite real). What's to say that her fake camera, in view but out of reach of thieves, is going to be less effective than catching images with multiple cameras attached around the outside of the house?

I'd guess as a deterrent, a realistic fake might be as effective...

One of our 4 cameras is outside but I'm not sure if it would be that readily spotted by someone calling at the house (L shaped bungalow). I opted for a more complete view of the front of the property than I'd get from the porch door area. That and I guess ease of fitting - a switch with POE does for the cabling to that one and the one in the living room. (The other 2 are 12v powered and one of them using wi-fi).

the way UK law works, you have to have camera visible and not pointing at other peoples' premises. Eg windows.

Just thought but how legal is it to have a fake camera visible and a covert camera covering a similar vista?
It would be one up on the criminal who might try to inhibit a camera, though if they think it is worth their while they are not that bothered with being filmed.

How robust is WiFi? I have seen a case on TV where cars were locked wirelessly but the crims were firing high power to block the transmission. Owners assumed the lock had worked and in the wee small hours the car is open to take whatever.

I wasn't aware of that Mr Red but from what you say, I believe I do comply with UK (where I live) law. It's just you would have to look above the sliding doors that open to the living room rather than the porch to the only generally used entrance. You can see it from the entrance gate but if your eyes were fixed on walking to the porch you might miss it.

Oh well it happened yesterday... As the PC, which is connected to a UPS, appears to have shut down correctly, I guess it's just co-incidence but the hdd with our pictures, etc. started acting up after a power cut yesterday. According to fsck, the disk is clean but it looks like the controller is on the way out - lots of lock ups and resets.

Anyway, I moved the disk to a USB caddy and for some reason found it works better (fewer resets, etc.) at USB 2 speeds (the device is USB 3). It took time but I've managed to back the photos and a handful of documents I need up so I guess I've been lucky.

I should have new hdd tomorrow and will think about the other bits the old hdd holds then. A number of CDs are in ogg format which isn't compatible with some devices here, stuff recorded from tv will come round again and some will never be watched, etc. I might be better off starting from scratch with some things.

Of course, I suppose the reorganise portion of "start from scratch" could be applied to my pictures too. There are a lot of "duplicates" (make more than one attempt at a shot) and quite a few where, when I look back, I can't work out why I took them or what they were about. Still there is stuff I want to keep (altough (to me) surprisingly few, eg. this one where I still think that's exactly what I wanted to capture. I doubt it but maybe the mishap will trigger a bit of a clear out later in the year...)
