USB Backup Plugin - Preemptive Query

  • Hey OMV Guru's, quick question for your all.


    So, I'm planning on having a few external USB drives (HDD's) to backup my central stuff on my OMV server, one external drive per one internal drive, so the external is an exact replica of the internal.


    My question is this.


    If I go down this route, is OMV/USB Backup using /dev/ identifiers or UUID's? Since I will be using multiple drives what I don't want to happen is two or more external drives (only one drive will be connected at any one time) to end up with the same /dev/sdx identifier and thus overwrite whatever is on disk B because it thinks it's disk A.

    OMV 4.x - D975XBX2 - Xeon X3220 - 4GB ECC Samsung DDR2 800MHz - Syba SI-PEX40064 SATA3 Card - 64GB Drevo SSD Boot Drive - Other drives...work in progress :rolleyes:

    UUID´s

    Since I will be using multiple drives what I don't want to happen is two or more external drives (only one drive will be connected at any one time) to end up with the same /dev/sdx identifier and thus overwrite whatever is on disk B because it thinks it's disk A.

    I have different USB and eSATA drives for different shares to backup. If a drive is connected only the configured shares are backuped to that drive. That works flawlessly, don´t worry! It is also possible to connect several drives at the same time.

  • No matter what, don't use the same filesystem label on the drives. Make sure they are unique.
