I used Norton Ghost for a few years, and actually did some real life restores from backed up images when my machine went through a catastrophic failure. That’s one of the highest marks you can have for backup software, there’s the old saying that backing stuff up is easy, but until you’ve actually had to do a restore you have no idea how valuable the backup is.
But anyway, I switched away from Ghost and to Acronis mostly because of other issues associated with Ghost. For reasons I was never able to troubleshoot, it caused horrific performance issues on my machine (which was very high end at the time) and after working at it for a long time, I just couldn’t resolve them.
I have Acronis TI 2011 and I basically have not had any issues with their “normal” backup procedure. I don’t bother doing a file backup because I can’t really imagine many scenarios where it would be useful. Computers don’t realistically tend to lose just one or two random files, if hard disk fails it has failed and you’ll want to do a full restore. Additionally, those backup images can be mounted and browsed as a virtual drive so you can grab any individual file you need via that route.
My C drive is my OS/applications drive and my D drive is just for storage of various media and other archival purposes. I use the Version Chain backup strategy for my C drive, and I run it every Wednesday at 9 AM (so I’m virtually always going to be at work and won’t need to use the computer.) I do validation on this one every time it runs, and I have it set to email me when it has finished. It’s generally a 100-150 GB backup and I will usually receive an email on my phone around 9:30AM saying it completed and validated, so it takes about half an hour.
My D drive I have set for differential backups, running every Monday at 9:00 AM. With this I have it create a full version after every 5 differential versions and I also have it do a validation and email every time it runs, as well as emailing me notification. Oddly despite it being a differential backup I do notice from looking at my old emails it tends to not finish up until around 10:30 AM, so it seems to actually take longer than the C backup even though that is a version chain backup which to my knowledge is actually a series of full backups. It could just be that the D drive is so much larger (500 GB +) and the validation on it might take much longer, not sure.
I’ve been running this backup system for awhile now, maybe 4-5 months. I used Nonstop Backup at first but no longer use it because I had very little luck with it. The first few days I had Acronis TI installed Nonstop backup worked great. Then it just broke and nothing I could do would fix it. It would start to do its backup, but would just display a message saying “Nonstop Backup Starting” and then it would never start. It didn’t impact my system performance or anything, so I left it alone for a few weeks. But once I confirmed it wasn’t actually doing anything I just killed it. While I’m happy with what I have, my experience with support for the issue I had is the same as Kaio’s, in that it is basically non existent.
So, it appears if you can get TI to work for you it’s great software. I do like it a lot, aside from the one piece that doesn’t work. However, if it doesn’t work, this isn’t the first person I’ve heard of who has had essentially unresolvable problems with the software. The closest I’ve ever heard to an explanation was mentioned up thread here as well, that Acronis has issues with HDD that have any sort of physical problem (minor number of bad sectors or etc) and maybe even specific HDDs from specific manufacturers that can cause their software to break.
