This guide details how to back up the data from your folders and nodes in Jelastic Cloud via the OpenStack Swift protocol to Swiss Backup, the backup solution in an independent Swiss cloud.

Introduction

• To back up data, an extension for Virtuozzo (Jelastic Cloud) is available in the node's add-ons.
  • Learn more about the extension (add-on) on Github.

Configure the Swiss Backup extension on Jelastic Cloud

Prerequisites

• Use Jelastic Cloud (at least one Jelastic environment must be active with the extension installed for your backups to be visible).
• Own an Swiss Backup Infomaniak space with an available device quota (minimum 1) for a Cloud backup.
• Add 1 device of type Cloud to obtain the OpenStack Swift settings.

To add the useful extension to Swiss Backup on Jelastic Cloud:

1. Log in to the Jelastic Cloud Dashboard of your server.
2. Go to the addons section:
   
3. Search for and install the Backup / Restoration extension:
   
   

Two types of backup are then possible and are detailed below:

1. Back up specific folders.
2. Create a snapshot of an entire node.

Back up specific folders

To back up specific directories:

1. Enter the username and password according to the information specific to your device.
2. Check Backup your data.
3. Check Backup specific folders
4. Enter the absolute path of the folders to be backed up in the Folders to backup field; you can specify multiple folders by separating each path with a comma, for example: /root/admin/, /home/user1/, /jelastic/containers/ (in this example, 3 folders have been specified)...
   

Next, you need to define the frequency of the backups (see below).

Back up an entire node

To back up an entire node:

1. Enter the username and password for your Swift device on Swiss Backup.
2. Check Backup your data.
3. Check Backup all files to back up the entire file system of a node; some files are automatically excluded:
   • the /dev, /proc, /sys, /run directories
   • file systems that are not mounted as part of the root partition, including virtual file systems
     

Next, you need to define the frequency of the backups.

Define the backup frequency and retention policy

Two options are available for performing the backup:

1. daily (at 8 PM UTC)
2. every hour (at the beginning of the hour, e.g., at 1 PM, 2 PM, etc.)

You can define the retention period for your backups in years, months, days, and hours. To keep your backups indefinitely, simply set the parameters to 0.

For example, if you perform backups every hour and set a retention policy to 1 year, 2 months, 4 days, 2 hours, this means that each backup will be available for a period of 1 year, 2 months, 4 days, 2 hours (=10322 backups). Note that backups are deleted every Sunday at 10:30 PM (UTC).

Restore backups

Restore data from a node

1. Log in to the Jelastic Dashboard of your server.
2. You will probably need to reinstall (restart) the add-on from the Marketplace:
   1. Click on Marketplace.
   2. Search for “backup”…
   3. Click on the "Backup / Restoration" add-on:
      
3. Once the extension has been added and the username and password for your Swift device on Swiss Backup have been entered, check Restore your data.
4. Select the node that contains the backup to be restored.
5. Select the backup to restore and the folder to restore it to.
6. Click on the Restore button:
   

Restore specific folders from a snapshot (CLI)

Each backup corresponds to a unique ID. You can include and exclude folders from your snapshots during a restore. To view your snapshots:

1. . /home/.config/swissbackup/openrc.sh
2. restic snapshots
   
3. Use --exclude and --include to restrict the restore to a subset of files in the snapshot; for example, to restore a single file: restore 79766175 --target /tmp/restore-work --include /work/foo

There are case-insensitive variants of --exclude and --include called --iexclude and --iinclude. These options behave in the same way but ignore the case of the paths.

Modify the backup configuration

To do this:

1. Log in to the Jelastic Dashboard of your server.
2. Once the extension has been added and the username and password for your Swift device on Swiss Backup have been entered, modify the configuration as desired.

The backup schedule is defined by a cron job, and backups are performed using the restic tool.

To manually modify the backup schedule (CLI), as the root user, run the crontab -l command to display the current schedule:

• the line containing retention-all.sh corresponds to the backup task
• the line containing purge.sh corresponds to the backup retention task

Example:

Modify the schedule using the crontab -e command.

You can modify the line containing the retention-all.sh or retention.sh script; these scripts are responsible for launching your backups. Please note: the cron jobs have been designed to avoid conflicts between backups and multiple deletions. Be mindful of the time required for backups and deletions…

Manually delete backups (CLI)

To do this:

1. Source the configuration file:
   . /home/.config/swissbackup/openrc.sh
2. Display available backups:
   restic snapshots
3. Delete the desired backup:
   restic forget IdBackup --prune
4. Delete all backups of a file except the most recent one:
   restic forget --tag folders --keep-last 1 --prune

Delete the backup schedule

This button allows you to delete the schedule for your backup:

Uninstall the Swiss Backup extension

You must delete the backup schedule (see above) before you can delete the Swiss Backup extension:
