Create Backup Schedule

This section explains how to create a schedule to automatically start backups.

Backup scheduling is based on full backups and incremental backups. For more information, see Backup Essentials.

Backup schedules use the same format as cron jobs. For more information, see https://en.wikipedia.org/wiki/Cron.

Procedure

Do not add or remove nodes on the archive volume or on the data volume being backed up while a backup is in progress.

Do not stop the database while a backup is in progress.

Follow these steps to create a backup schedule: 

  1. In EXAoperation, go to Services > EXASolution and click the database instance for which you want to create the backup schedule. The Database Instance screen is displayed.

  2. Click Schedule to create a backup schedule. This displays the EXASolution Backup Scheduling screen.

  3. Set up a backup schedule using a combination of the parameters from Backup Schedule Settings. Separate multiple entries with commas.
  4. Select the Active checkbox and Add check boxes for the record you are adding, and click Apply.

For Sunday, you can choose any of the two (0 or 7) options from the value range.

Archive Select the archive volume the backup will be stored on. N/A  
Level The backup level, such as full backup, or incremental.

0-9:

  • 0 - full backup
    1 - incremental backup to level 0 backup
  • 2 - incremental backup to level 1 backup
  • etc.
  
Expire

The duration of time until the backup will expire.

 N/A To make a backup available for one week and three days, set Expire to "1w 3d".
Comment A description for the backup. N/A "Weekly full backup."

If a local archive volume runs out of free space, expired backups will be automatically deleted. Expired remote archive volumes will not be deleted by this function.

Example: Weekly Backup with Daily Incremental Backups

The following is an example of creating a weekly backup with daily incremental backups. The following is a suggestion for a backup schedule:

  • Full Backup on Sunday at 00:00 (level 0), with a retention time of 1w 3.
  • Incremental Backups every day of the week at 00:00 (level 1), with a retention time of 3d.

In this backup setup, a full backup (level 0) is done on Sunday at midnight. The backups on each week night (level 1) back up all changes that occur since the full backup. The backups are stored in an archive volume within the cluster.
