Backups and howto

This Yunohost server is backed up onto two separate USB drives, both of which are on-premises. Several attempts have been made to perform an off-premises backup using both Borg and Restic, but I have found them to be more difficult than they’re worth, so I am doing backups on-site using the built-in Yunohost backup and recovery service and Restic, both to their own USB drives.
Drive 1 (Drive label: YNHRECOVERY)
This backup uses the built-in Yunohost backup and recovery service. A simple cron job is used, detailing the time and what is to be backed up.
FULL BACKUP
Time: Midnight every Wednesday and Sunday
What: EVERYTHING. (accept multimedia items like videos, photos and music) This is a full backup. Everything is checked off in the Yunohost backup service. There is a .nobackup file in the folder /home/yunohost.multimedia. This blank file prevents this folder from being backed up.
OTHER ITEMS BACKED UP
Time: 4 AM EVERY day.
What: User home folders and emails.
Drive 2 (Drive label: DATARECOVERY)
Restic is a backup service that can be installed from the CLI or through the Yunohost application catalogue. On this server, it has been installed using the CLI.
The backup used to be a cron job, but recently the excellent Restic GUI, Backrest, has been installed and is now in use. Using this app, you can create Restic repos, view and download the contents of a repo, set the times of the backup and set retention.
ALL items in the folder - /home/yunohost.multimedia are backed up to drive 2 DATARECOVERY
Time: 3 AM every Saturday
What: /home/yunohost.multimedia
Below I have kept some useful Restic commands, just in case...! Well, you never know...
Where is the Restic app located? Type: which restic will show you where the app is located on your drive.
Where is my Restic repository located? The Restic repository is located at media/datarecovery/restic. This is a symbolic link from the Restic directory on the main drive. The physical drive is a USB spinner labelled “datarecovery”. 
What is the latest installed Restic version?
Type: restic version. This will tell you the current version, which right now is 0.19.1 (Note: The Restic version is not the same version that appears in Backrest as shown on the top left corner of the app, which at the time of writing is v1.14.1)
Can I update Restic? Type: restic self-update. If there is an update available, it will be downloaded and installed.
Has the backup happened? Type: restic check -r /media/datarecovery/restic
How do I change the backup schedule? Type: crontab -u root -e Nano will open, and you can edit the time and contents of your backup. This cron job now runs the yunohost backup to drive 1 'YNHRECOVERY' only.
Can I see the snapshots? Type: restic -r /media/datarecovery/restic snapshots
Can I see the contents of the snapshots? Type: restic ls (snapshotID here) --repo /media/datarecovery/restic
Can I mount the snapshot? Type: restic -r /media/datarecovery/restic mount /mnt/restic
NOTE: For most of the above commands, you will require the restic password that you set up when you created your repository, etc.
