I will explain briefly how to move the Backuppc __TOP_DIR__ to another disk.

• Copy the real Files (the pool or cpool) to the new disk

I do prefer rsync but other method are possible (simple cp, tar, …) <source>

   cd /var/lib/backuppc 
   rsync -aq --exclude=pc/ ./ /new_drive/new_backuppc/

</source>

be patient this can be long… to see what’s going on replace -aq by -avP

• Use an Internal backuppc command (BackupPC_tarPCCopy) to copy each PC hardlinks structure

this is also very long treatement. A huge amount of small hardlinks are read and relinked to the new destination

<source>

   su __BACKUPPCUSER__
   cd NEW_TOPDIR
   mkdir pc
   cd pc
   __INSTALLDIR__/bin/BackupPC_tarPCCopy __TOPDIR__/pc | tar xPf -

</source>

too keep an eye on the progress I’ve found a small tool pretty handy to monitor piped data: “bar”

<source>

   /usr/share/backuppc/bin/BackupPC_tarPCCopy /var/lib/backuppc/pc | bar -dan -bs 4096 | tar xPf -
