===== Copying a AFFA USB hard drive archive to a new disk =====
Affa uses copious amounts of hard links to compress and preserve disk space for its backups. If you are in the situation where you want to copy such a disk archive to a new (bigger) disk, you need to ensure that the hard links are copied correctly or the destination copy may became significantly bigger than the total of the source archive.
One way to copy across file systems (i.e. two different USB disks) and preserve the hard links is as follows:
* mount both USB drives but with different mount points. e.g. /media/backup1 & /media/backup2 and then:
mkdir /media/backup2/archive
cd /media/backup1/archive
tar cpf - . ! ( cd /media/backup2/archive && tar xpf - )
where '''archive''' is the name of the AFFA job you want to move to the other disk.
