Anyone tried duplicity? It fits the bill. It creates encrypted chunks and
still minimizes the network traffic for incremental backups, just the way
Importantly, it does not expect the server to support any special
protocol, can work with scp, rsync, ftp, amazon s3 and perhaps more, and
of course with local filesystem as the target.
I might use it differently, by creating the chunks locally and rsync-ing
alternate ones on different cloud storage services if I want additional
Due to incremental storage style, it can recover previous snapshots by
timestamp or can restore backups in parts as well.
The only drawback (rather apparent bug) I find is:
1. Create a backup. Say now you realize you accidentally left a large file
in the backed up directory which you didn't want to backup.
2. Now delete the large file and do an incremental backup.
3. Now use CLI options (see remove*) to eliminate previous snapshot (use
extra-clean, force whatever with it). I don't find the backup space
reducing by deleting those extra chunks.
Barring this issue I find this to be a good solution.
Web searches show discussions on this issue and some claim additional
options like --extra-clean --force etc worked for them, though nothing has
worked for me really.
If anyone gets a chance to try above scenario and succeeds in trimming the
backup for above scenario, please update on the thread.
