Hi all! Please help a beginner with the backup issue.
1) First question. My scheduled tasks include rebooting the NAS once a week. Sometimes after a reboot the drive letters change for some reason. In the backup plugin using the dd full disk method. I must specify the root disk that needs to be backed up. How will this backup be performed on a schedule if after the next reboot of the NAS the drive letters themselves change? I cannot specify the UUID of the disk, because the system disk has three partitions and each partition has its own UUID. I currently have /dev/sda
2) Second question. After backing up using the full disk method, eight files appeared in my destination folder.
/omvbackup/backup-omv-2024-04-29_00-38-08.ddfull.zst
/omvbackup/backup-omv-2024-04-29_00-38-08.sfdisk
/omvbackup/backup-omv-2024-04-29_00-38-08.grubparts
/omvbackup/backup-omv-2024-04-29_00-38-08.grub
/omvbackup/backup-omv-2024-04-29_00-38-08.espdd.zst
/omvbackup/backup-omv-2024-04-29_00-38-08.packages
/omvbackup/backup-omv-2024-04-29_00-38-08.fdisk
/omvbackup/backup-omv-2024-04-29_00-38-08.blkid
In the future, after a possible breakdown, I will boot from a live USB. Which command should be correct and which file should I specify as the recovery source?
Thank you all in advance for your help!
