Snebu ( http://www.snebu.com http://www.snebu.com and https://github.com/derekp7/snebu https://github.com/derekp7/snebu ) is a Linux backup system that works kind of like rsync snapshot backups (i.e., similar to rsnapshot). Except it stores backup sets meta data in an sqlite database, and the files are stored as lzo compressed objects. Other than the standard features such as backup retention schedules, it has a number of small features that I haven't seen in a lot of similar backup utilities: * Path rewriting (grafting) -- this lets you mount an LVM snapshot somewhere, and the backed up copy can be stored referencing the original path (i.e., if you backup a snapshot of /srv/mydbfiles mounted on /mnt/snapshots/mydbfiles, you can tell it to store it on the backup server as if it was backed up from /srv/mydbfiles). This also works the other way for restoring files. * Safe expiring of old backups -- Let say you haven't backed up a particular host for a number of months (i.e., it has been decommissioned). When you tell the system to expire all backup older than 6 months, it will by default keep the 3 most recent backups [this number is tunable on the command line]. * Multiple user / granular permission support [ in the development branch, should make it in the next release ] -- You can give a given user ID the ability to backup but not restore, or backup and restore but not purge old backups, etc. That way if a host is compromised, you can ensure that an attacker can't delete backups from that compromised host. * If used in client/server mode, you can back up a client from the server without installing anything other than an SSH key (it just calls GNU find/tar on the client). Things missing that are currently being coded up: * Client side encryption * Multiple backend support (to support tape or cloud replication) * Local shadow copy -- lets you back up a laptop to a network server, but also do incremental snapshots to a local USB device when not on the network, and sync that to the network copy periodically.
