Vorteil von pbzip2: Multicore Unterstützung.

An pbzip2 wird mittels dem -p Switch definiert wieviele CPU-Kerne benutzt werden dürfen. In dem Beispiel sind es zwei (-p2).

Backup:

	Source code
1	nohup dd if=/dev/<LVM Gruppe>/<LVM Disk> bs=512K \| pbzip2 -p2 -9 > <Backupname>.bz2 &

Restore:

	Source code
1	nohup pbzip2 -p2 -dcf <Backupname>.bz2 \| dd of=/dev/mapper/<LVM Disk in welche das Backup gespielt werden soll> &

Leider ist es inkompatibel zur alten bzip2-Version. Hatte das mal mit dem Fastdl probiert. Der Client konnte die Dateien dann leider nicht entpacken.
