Digitalcarnage

digitalcarnage.co.uk a self-hosted, homelab server based in the United Kingdom.

Start Here

The server software used is the freely available Yunohost server software which uses Debian Linux. There are several applications hosted on this server, some public, and some private. See this page for the full list of applications currently installed.

The hardware is a Dell small form factor (SFF) 7020 desktop PC with an i7 4770 processor, 16 gigs of RAM and a 2TB hard drive. (An old-fashioned spinner!). There is a nightly mail and data backup and a full backup at the weekend. The backup is a simple cronjob that performs a backup to an external 1 gig solid-state drive. A second 1 gig drive is used as a second backup using Restic.

There are several domains hosted on the server that are registered through iWantmyname. See the full list of domains here in this chapter.

SSO users can login into the server here. For details about installing yunohost and creating your own self-hosted server, you can just jump straight in here to get started.

Server Applications

There are several user applications for use on this server, some of them can be used by the public, but for the most part, they are for private use. However, an account can be created on those apps by asking the admin to create one for you. SELF-REGISTRATION IS DISABLED on all apps for obvious reasons!

Backups and howto

This yunohost server is backed up onto two separate USB drives both of which are on-premise. Several attempts have been made to perform an off-premise backup using both Borg and Restic, but found to be more difficult than it’s worth!

Drive 1 (Drive label: YNHRECOVERY)

This backup uses the built-in Yunohost backup and recovery service. A simple cronjob is used detailing the time and what is to be backed up.

FULL BACK UP

OTHER

Drive 2 (Drive label: DATARECOVERY)

This drive uses the Restic backup/recovery application, which is a third-party application. Again, a cronjob is used to detail the times and what items are to be backed up.

The difference between the two backups is that the Restic backup is incremental and the last three backups are kept. The Yunohost backup is not incremental; therefore, some administration must be done to prune the drive as it becomes full.

HOW TO USE THE RESTIC BACKUP SERVICE (BASICS)

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.

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 can be found 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 restic 0.17.3

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.

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.
