* Local backup

[[https://restic.readthedocs.io/en/latest/index.html][Restic]] is used to create incremental backups.
Host ~raspberrypi4~ is set for backing up ~glusterfs~ files.

All ~glusterfs~ files are mounted under =/mnt=.
An ~NFS~ drive is mounted under =/data/backup= as the backup destination.

=/etc/fstab= entries:
#+begin_src
localhost:/dockervol /mnt glusterfs defaults,_netdev,noauto,x-systemd.automount 0 0
192.168.1.1:/mnt/sda1/backup /data/backup nfs defaults 0 0
#+end_src

** One time backup

Apply =backup.job.yaml=.

** Scheduled backup

Apply =backup.cronjob.yaml=.

** Restore

Apply =backup.pod.yaml=.
It creates a =restic-cli= pod on ~raspberrypi4~.
=kubectl exec -it restic-cli -- /bin/sh= gives you a shell in the pod's container.
Select the snapshot id by running =restic --repo /data/repo snapshots --insecure-no-password=.
Run =restic --repo /data/repo restore <snapshot_id> /data/glusterfs --insecure-no-password= to fully restore from a snapshot.

* Remote backup - WIP

=kubectl apply -f backup.remote.pod.yaml=
It creates an =rclone-cli= pod on ~raspberrypi4~.
=kubectl exec -it rclone-cli -- /bin/sh= gives you a shell in the pod's container.
Run =rclone -vvv --progress --stats-one-line --max-stats-groups 10 --log-format date,time,UTC,longfile --fast-list --buffer-size 256Mi --oos-no-check-bucket --oos-upload-cutoff 10Mi --multi-thread-cutoff 16Mi --multi-thread-streams 3000 --transfers 3000 --checkers 64 --retries 2 --oos-chunk-size 10Mi --oos-upload-concurrency 10000 --oos-attempt-resume-upload --oos-leave-parts-on-error sync /data/repo oos:backup -vv=
