Re: [rdiff-backup-users] rdiff-backup and rotated external drives

[Dominic Raferd]

Dan, with your strategy each external drive will contain 6 sets of daily 
incremental changes and then 1 set of changes which covers 8 days 
(repeated every fortnight) - and they will be different from one 
another. It's workable but not ideal. John's strategy is more logical.

Do you have the possibility of running rsync from the server direct to 
an offsite location? That way you could keep your rdiff-backup 
repository on your server and regularly sync it to the offsite location, 
so no one has to run around with disk drives.
