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

Introduction

• To back up the data, an extension for Virtuozzo (Jelastic Cloud) is available in the node's add-ons.
  • Learn more about the extension (add-on) on Github.
  • Do not search for the extension in the Marketplace, as it is not available there.

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).
• Have an Swiss Backup Infomaniak account with an available device quota (minimum 1) for a Cloud backup.
• Add 1 device of type Cloud to obtain the OpenStack Swift parameters.

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

1. Log in to the Jelastic Cloud Dashboard of your server.
2. Go to the node's add-ons section:
   
3. Search for and install the Backup / Restoration extension:
   
    

Two types of backup are then possible and 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; it is possible to 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)…
   

Then, 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 frequency and retention policy for backups

Two options are available for performing the backup:

1. daily (at 8 PM UTC)
2. every hour (at the beginning of the hour, for example 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 of 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. 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.
3. Select the node that contains the backup to be restored:
   
4. Select the backup to restore and the restoration folder.
5. Click 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 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 schedules:

• 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 launch your backups. Note: the cron jobs are designed to avoid conflicts between backups and multiple deletions. Pay attention to the time required for backups and deletions…

• Learn more about restic: restic.net

Manually Delete Backups (CLI)

To do this:

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

Remove the Backup Schedule

This button allows you to remove the backup schedule:

Uninstall the Swiss Backup extension

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