In short, no. All folders and files under /var/lib/backuppc must be on the same filesystem. You could move /var/lib/backuppc to /media/secundary_disk and then remount or bind mount that to /var/lib/backuppc. Assuming the new disk is bigger than the old disk... > RAID1 it's good idea but i can't modify the hardware of the server. RAID1 wouldn't increase your storage capacity anyway. However, you could use RAID1 without modifying the hardware (using software RAID). In any case, you would be much better off doing 2 things: 1) Use the second hard drive for ALL backuppc data storage, or adding another hard drive big enough to do this. 2) Use 2 hard drives of equal size in a RAID1 mirror (or 3 or more in a RAID5 or RAID6) to ensure that your backups will survive a disk failure. RAID1 or RAID5 will certainly reduce the likelihood of data loss, but I'm not sure that either RAID configuration ensures data protection. I've read arguments that, as the size of drives increase, the likelihood of RAID5 protecting data decreases. An offsite backup of your data is your best insurance. This can be a contentious issue, and I am no expert.
