+===== 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.
