Hello,

I'm doing a similar backup but with 3 disks :

 - 2 disks (A and B) connected as RAID.
 - a third disk.

When I want to change a disk, I replace B with C and I rebuild the RAID. :)  I'm using mdadm on Linux


Like this, I limit a lot risks of destructions of backup.

Hope this helps.

    Hi All,

I would like to configure the Bacula in following way
  • use 2 external hard disks connected over the USB
  • change these 2 HDDs once per week (let's say on friday afternoon)
  • every day doing a backup - incremental (of several servers)
  • once per year do a full backup
  • if one external HDD dies - I want to loose the backup only for one week
    • i.e. on every HDD, there should be one full backup
    • the incremental backup after the disk change (friday) should follow the last increment on that HDD (not on the other one)
    • one can restore correctly the data only from 1 HDD

Is such a configuration possible? If yes give me a rough idea, please. I hope I can find out the details.


Martin
