I’m moving my duplicity backups to restic after the latest Chaosradio episode because encryption is easier, reducing the looming fear of having to restore a backup. Thanks for your hard work!
For duplicity, I had separate jobs for a few folders, backing up into separate Backblaze B2 buckets.
With restic, I combined all of the folders into one repository/bucket for scripting convenience. The first snapshot of ~350 GB finished with this restic incantation:
restic -q --json /mnt/disk1 /mnt/disk2
Now that I got the backup working I wanted to add
restic -q --json /etc /mnt/disk1 /mnt/disk2
However, restic apparently wants to upload everything anew if I do that. It starts processing lots of music files from the storage disks and
percent_completed increases veery slowly.
Undoing the change and running restic again will finish as quickly as I expected. It just uploads a few changed files.
Am I doing it wrong? Is there a better way to add folders to the backup?
