I'm looking for a reliable backup solution on Windows, something with a feature set similar to Yadis.
I've been using CrashPlan for 2 months, but their software lost more than 1TB of my data, that's why I'm looking for alternatives.

Requirements:

  • Real-time local folder-to-folder backup
    I don't need online features, I want to use this to duplicate my files between my local disks.
  • Versioning support
    Should be able to choose how many versions to keep of the files.
    Or at the very least, it should keep deleted files until a specified time or space limit gets hit, and delete them afterwards automatically.
  • Plain backup
    I want to be able to open the backup without special software. No proprietary file formats.
  • Shadow copy
    Backup every file, even locked/system files. (Yadis fails this one)
  • AutoStart
    Doesn't need to run as a service, but that's a plus.
  • Actively maintained
    I don't want to use discontinued products.
  • Relatively cheap
    Should be under $100 for one-time payment, or $60 for a yearly fee.

Optional requirements:

  • External disk support
    Shouldn't have any problem using external disks, at least on the source side.
  • Low resource usage
    I'm not really comfortable with something that eats 1GB of my RAM.
  • Compression support
    Preferably ZIP, but I'm not picky about this. Any ordinary everyday format is acceptable.
  • Freeware or Open Source
  • Linux support
  • Cloud storage

  • @nidunc I'm asking it here, because it was considered off-topic on SuperUser, and I think it's more reasonable to ask it here. But it's a good idea to link these together. – Borda Jun 11 '14 at 21:58

    For the long term storage, it's generally a better idea to let the file system handle the compression, i.e. to backup into a compressed NTFS folder rather than into a .zip/rar file. – Angstrom Jun 14 '14 at 20:50
  • Did you inform CrashPlan about the data loss, in order that they can do do something to prevent it happening to others? – Mawg Feb 12 '16 at 8:45

    @Mawg Yes, I did. They couldn't really care less actually. Their cloud still had most (but not all) of my files, only their hybrid backup lost them locally. Downloading 1TB with their amazing speed of around 30-100kb/s wasn't a pleasurable experience, that's why I've switched to another app. It's easy to prevent, just don't use the local hybrid backup feature. – Borda Feb 12 '16 at 18:27

For anyone who needs reliable one-way data duplication on Windows, I can highly recommend: Bvckup 2

Positive:

  • Meets (nearly) all the requirements
  • It uses delta copying, it's extremely fast, and very resource friendly.
  • Backing up ~300k files totaling ~2TB I've never seen it go over 150MB of memory usage, most of the time it stays in the 20-50MB range.
  • It has no problem using (and tracking) external storage.
  • At the time of writing a Personal license costs $19.95, and they even have a free beta version.

Negative:

  • It doesn't support full versioning, but it does keep deleted files for a configurable amount of time
  • No compression support
  • No Linux support
  • No cloud support

But these were listed as optional, and for versioning it still meets the "Or at the very least" expectation.

    That's what I use too (+1). I couldn't find a FOSS app that comes anywhere near it, despite a lot of searching. You forgot to mention that it supports MS's Volume Shadow System,. so that it can copy files which are in use. – Mawg Feb 12 '16 at 8:47

It sounds like what you really need is to modify your storage to use a RAID system - if it is configured above RAID 0 then a failed drive is not a problem and results in no data lost.

It also sounds like you would like a versioning file system - several operating systems offer this but AFAIK none from Microsoft. Wikipedia lists several experimental versioning file systems for Linux such as:

  • ext3cow
  • NILFS
  • Tux3
  • Next3

You could also take a look at WebDAV possibly combined with Subversion Autoversioning.

  • You mean RAID 1, right? RAID 0 is absolutely not failure proof. I'm already using RAID 1 for my system drive, but it's not really a backup solution. If a file gets deleted or corrupted, it'll propagate across drives, and of course it doesn't have versioning. That's why I'm looking for a backup solution on top of that. Call me paranoid if you want ;) – Borda Jun 11 '14 at 22:02
  • @Borda That is why I said "above 0" - real time back up of a file system == RAID & Versioning FS. – Steve Barnes Jun 12 '14 at 5:17
  • Oh, sorry, I misunderstood that part. Know that I know what you meant, it makes sense. Never heard of these filesystems, the idea seems good, but I'm still looking for a Windows solution. – Borda Jun 12 '14 at 15:43
  • You can mount WebDAV file systems from most flavours of MS Windows. – Steve Barnes Jun 12 '14 at 16:38

Free File Sync is a great Open Source application that really does this well http://www.freefilesync.org/faq.php. The features are really rock solid.

Warning: you must be careful to not install the yucky OpenCandy advertisement crap. You may now be able to get a "clean" build without ads by contributing to the developer. Or you can get a Windows binary version compiled from the source , without the ads, called MinFFS on GitHub, https://github.com/abcdec/MinFFS/releases, but that version doesn't support shadow copies.

Fantastically, it also can do comparison of file content not just modification time and size. This can help you spot corrupted files.

And this is nifty: ""FreeFileSync runs on Windows XP/Vista/7/8/8.1/10, Mac OS X 10.7 and newer, and all major distributions of Linux."

  • Surprisingly no comments on this one can you please add billeted pluses and minuses I m looking for open source solution – SeanClt Feb 23 '16 at 12:27

  • According to the website, only the enterprise edition supports managing more than 1TB of data, and that costs $299.99, which was way out of scope for this question. – Borda Feb 12 '16 at 18:32
