===== 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.
fdisk /dev/sdh
fdisk /dev/sdh
You'll most likely find an existing vfat dos partition, which you have to delete first. In the following we assume, that you have created a single partition ''/dev/sdh1''.

−* now format the drive with an ext3 filesystem, if prodbox has ntfs utils installed the usb can also be formatted ntfs, see [[USBDisks|USBDisks#NTFS]]
