Re: [Duplicity-talk] backup design question

Thanks guys (including Joel), your responses were very helpful.  Any reason why I should be using a protocol other than FTP for the off-site transfers?

Here my understanding of some benefits of each:

FTP
- less overhead
- simply way to "jail" the users' access

SSH
- secured tunnel (passwords, for instance are not sent in cleartext)
- enhanced security to prevent brute force cracking of passwords
- can use keys for authentication

What am I missing?

The suggested way of backing up using duplicity is to target backup to
the local server using duplicity, then to use rsync to synchronize that
backup with the remote site.  This has two advantages, one in that the
local backup is available for rapid recovery if the need arises, and the
remote backup is available after a site disaster.
