I have a main backup server running rsnapshot, with ~2TB of backups stored on it. After the nightly backups, I copy the contents of the rsnapshot directory to an offsite server, using rsync -aH --delete /source /dest
. However, this seems to copy the entire contents of the backup directory every night, as the offsite copy takes ~9 hours to complete.
I assume my rsync command doesn't have the right switches, but there may be something else I'm missing. Any ideas?
