[gentoo-user] Encrypted Backups

[Florian Philipp]

Hi list!

I'm in need of a backup tool and an advice would be helpful because I 
need some special functionality.

I want to make backups from my laptop to a cardreader (pcmcia), making 
daily full and hourly incremental backups *if the card is plugged in* 
(which might not be the case for as long as two days).

Additionally I need some kind of encryption. The key could reside on my 
home partition which is encrypted itself and maybe pam-mount + luks is a 
solution but I'd like to hear some opinions on that topic.

If no one comes up with a better solution, I think two cronjobs with 
tar, gpg and find will do it, don't you think? The alternative would be 
rdiff-backup with some kind of encrypted and possibly compressed file 
system.

Thanks in advance!
