I have about 30TB of data stored on two drives which I would like to backup to a QNAP TL-D800S enclosure (8 drive JBOD storage connected via 2x SFF-8088 cables) which mounted only for the purposes of making the backup and subsequently stored offsite. I know relying on disk as backup isn’t ideal, but it’s what I have available at present and it’s better than no backup.
For clarity, the drives containing the 30TB to be backed up as well as the QNAP would be connected to the same headless server that Duplicati is installed on.
30TB source is mounted as :
QNAP target drives are mounted as mounted as:
The operating system sees the 8 drives in the QNAP as 8 discrete drives (and I want to keep it that way rather than risk one huge JBOD or bothering with a RAID array which isn’t backup to begin with.
Is it possible to have Duplicati write the backup out to the QNAP drives, filling one, then the next until the backup is completed?
On the assumption (1) is possible … As some of the drives in the QNAP contain data I’d ideally prefer not to override, is it possible to point Duplicati to a folder on each of the 8 drives into which to write the backup?
