I'm trying to script a backup system for several servers, some Windows, some Linux. I'd love to be able to use rsync but I can't (at least not in all situations, since some servers I can't install rsync to, and some are Win servers).
To add a wrinkle, some servers I have SSH access to, and some I have only FTP.
I've tested with wget in FTP mode with the "timestamping" option, and it seems to work pretty well regardless of platform. I'm also investigating rdiff-backup, though it appears that SSH is required.
Are there other options that may be more robust/reliable, that will do incremental backups regardless of platform and can function on either SSH or FTP?
Thanks for any ideas
