One time backup and restore
Just ran out of room on my tiny SSD, so figuring out a migration path using rsync archive mode. Mounted the SSD on my Mounted a large HDD from the bygone era for temporary storage, and began copy:rsync -a /media/henry/<SSD folder> /media/henry/<HDD folder>
Since the SSD is mounted on USB, rsync goes on for a couple of hours.
Copying from the HDD to another, bigger drive should work just like above (but in reverse direction of course):
rsync -a /media/henry/<HDD folder>/. /media/henry/<new SSD folder>
Incremental backup
Restrict rootfs backup to skip kernel generated fs, and backup the /mnt separately. The script to run in the backup folder is then is then
sudo cp -al latest `date +%F`
sudo rsync -aAX --delete --exclude={"/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} / latest/rootfs
sudo rsync -aAX --delete /mnt/opt latest
sudo rsync -aAX --delete --exclude={"*.vdi"} /mnt/work latest
I omit the Virtualbox guest's virtual HDD from the backup set, because that file changes every time, and is large.
