However, hard link support (in the "two files that are hard links to the same inode will only be backed up once" sense) is disabled by default.

It works well for us backing up hundreds of Linux systems. It supports hardlinks and even relies on them you might say... "Using rsync and hard links, it is possible to keep multiple, full backups instantly available. The disk space required is just a little more than the space of one full backup, plus incrementals." http://www.rsnapshot.org/ -- Mark D.

I'm curious if there is any mindshare > overlap at all. I almost exclusively use Duplicity. I find its seamless integration with GnuPG and cloud storage solutions (specifically Rackspace Cloud Files (and hence Openstack storage) as well as Amazon S3) extremely handy. I used to use Bacula (and haven't completely phased it out anywhere, but that's only due to lack of time, not missing functionality or anything like that). I'd throw my backups on a server with lots of space and then I'd run a script that would copy full volumes to Amazon S3. Eventually, I got severely fed up with having to maintain this box for temporary storage. My only gripe with Duplicity is that it doesn't detect hard linked files, but I hardly ever use hard links anyway. It's also worth noting that even though duplicity is one of the very, very few backup tools that *says* it doesn't support hard links, it's far from the only one that doesn't actually support it. Many other backup tools are simply blissfully unaware of this shortcoming in them. -- Soren Hansen | http://linux2go.dk/ Ubuntu Developer | http://www.ubuntu.com/ OpenStack Developer | http://www.openstack.org/ -- ubuntu-server mailing list ubuntu-server@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam

For server backups I'd recommend TurnKey Backup and Migration [1], a pain-free, smart backup and migration system that just works. No configuration required. > Is the program duplicity [1] (upon which Déjà Dup is based) well > regarded in the server community? I'm curious if there is any mindshare > overlap at all. TKLBAM uses duplicity as its backend, so in general I'd recommend it. Disclaimer: I'm one of the TurnKey Linux developers.
