My bare metal backup / restore script.

Hairyplotter · 2024-04-16 04:07:41

I can't stress enough the importance of having an up to date backup of all of your data.
Too many times I have done "rm -rf" -> realize I was in the wrong directory -> cried for days because I didn't have a backup of the data I nuked.

This script is a full backup using rsync. I might add an option for incremental or differential backups in the future.
This script saves my source device partition table to a file in the root of the backup directory.
This script creates a full restore script in the root of the backup directory.

For a little context. My laptop has 2 internal SSD drives that I link with LVM. I have a docking station that I use with a combination of SSD and SATA drives. (I NEVER dispose of a working drive, I retire them when they die) I also have a 4TB USB drive. I use a combination of all of these for backing up my data which explains the long list of potential backup destinations in my script as well as the source devices.

My entire backup strategy is built around this setup, but my script can easily be edited to conform to virtually any configuration.

ALL of my external drives are mounted in my /home under a directory called "MountPoints", each drive having a listing in my /etc/fstab:

UUID=09c5f8df-7a4e-48df-b98c-606a831213d4 /home/robert/MountPoints/USB4T-PART3 btrfs noauto,users 0 0

The documentation isn't finished, that is on my [TODO] list.
Also, since all of my UUIDs are fixed, there is no need to do genfstab after the restore, so activating the swap partition in my restore script is kinda pointless.
since leaving it in is harmless, I haven't gotten around to removing it, I'll do it in a later revision.

The use of BLOCK_DEVICES is overcomplicated. 'lsblk -n -o MOUNTPOINT' would obviate the need for cut.
