I am ready with my first TrueNAS project. TrueNAS is running as a virtual machine on proxmox (passthrough the whole controller, see my other post).
For Backups I use two external usb drives with encrypted zfs pools. If I want to restore the entire backup I assume adding another job which does the replication vice versa is the way to go. I am wondering what to do If I want to restore single files. Is there another comfortable way to do this beside cp in cli?
I would also like to know how to test the backup or restore on another machine.
Until now I tested the backup on another machine with proxmox and another TrueNAS vm. It was necessary to detach the pool. On the other machine I had to unlock the pool with the encryption passphrase. If I am switching between the backup hdds that process needs to be done “manually” every time. Is there a possibility to automate this because I am afraid to broke my backup if I forget about detaching in the future.
Thank you for tips.
