backuppc notes

Transfert whole datas to another server or disk

cd /var/lib/backuppc
tar cpf - . | ssh xxxx 'tar xpv -C /var/lib/backuppc'
cd /var/lib/backuppc_old
tar cpf - . | tar xpv -C /var/lib/backuppc

backuppc on zfs-on-linux

forget it, absolute performance mess

the workaround is to use a zVOL and format it in ext4:

zfs create -s -V 600g rpool/datas/backuppc_zvol
mkfs.ext4 /dev/zvol/rpool/datas/backuppc_zvol
tune2fs -m0 /dev/zvol/rpool/datas/backuppc_zvol
# /etc/fstab
/dev/zvol/rpool/datas/backuppc_zvol     /datas/backuppc    ext4    rw,noatime 0 0
