Backup/Clone OS Drive

ZimaOS
1

Hi, a complete newbie to the HomeLab/NAS scene and I am just in the process of setting up a Mini PC, with 4 x 2TB M.2 NVME and 1 x 512GB M.2 NVME and will be using ZimaOS with the *arrs, Emby, Immich and Nextcloud primarily.

Anyhoo, my question is with regards to the 512GB NVME that will be where the OS will be installed. I understand that the 4 x 2TB drives have some safeguards when set up as Raid 5, but what about the OS drive? Is there a built in backup or clone feature? I would like to do a periodic baclup or clone onto an external drive but would this actually work? If the OS drive failed and I didn’t have a cloned drive to replace it, then i’m guessing a reinstall of the OS would mean difficulty in keeping the already created Raid drives?

I’ve probably gone all around the houses trying to explain myself, but i’m basically concerned about what would happen to the data on the Raid drives should the OS drive fail?

Usually you need run backups of the OS drive either from external media, or using software that can snapshot the drive and save the snapshot. If the OS drive is “doing stuff” between the time the backup start and end its possible your backup will not work as a restore.

The data on the RAID drives should be secure, and once you re-install the RAID software it should see the existing raid and work, but It may be best for others to confirm that as I use mine as separate drives not a RAID array.
