Hmm.. noticed one downside with this: it doesn’t auto-purge or limit. Any way to set that up? (e.g. as in JungleDisk: max file-size for versioning to kick in, remove after x days, keep at least/at most regardless of age)

No, I don’t believe there is any way to have it remove files after a specified period of days. You might be able to contact the developer and request that for a feature though.

Also, doesn’t it lock the files when backing them up? 7-zip would keep them locked longer than zip, so zip would be preferred if you do many saves I think?

It’s probably the inability of the software to “resume” the connection at a timeout… or the resume function is somewhat buggy.

Cobian is an awesome app… however, it freezes once in a while. Tonight I was uploading a 200MB file which took a few hours (slow server)…and it froze at 96%

Sounds like a bug… you should definitely report that to the developer.

You can use a paid service for SVN for reliability (such as beanstalkapp.com, fogbugz.com), but since you have to commit manually, I don’t think that is an equal or better solution for easily keeping revisions of documents.

Have you try it? Is it better than Cobian?

I haven’t tried FileHamster myself, but from what I can tell Cobian is more full featured as far as a backup utility goes. You can do things like backup to/from an FTP, which few apps can do.

The only problem for this program is the main window some times freeze (although the backup process still running). Maybe because I use Vista with UAC on. End task and launch the program again usually solve the issue.

Using Cobian you don’t have to do the backups locally… if you’ve got another computer on your network it would be just as easy to setup as doing it locally. If you just want a revision history for something like a report you’re working on I don’t think there’s any sense in setting up a CVS or Subversion server.
