Backup archival involves creating copies of backup files for long-term retention. The archival process is needed to avoid losing backups after a certain period and ensure the availability and accessibility of data in the event of data loss, system failures, or disasters.
- This is the backup data that can easily be recovered as it is available for performing restorations.
- Backup retention for indexed data is set to 6 months at default.
- You can manually specify the period for which the indexed data needs to be available for performing restorations at Retain indexed data for field.
- Minimum retention period for indexed data is 3 months and maximum is 12 months.
- This is the backup data which has been archived for storage. You can index archived data at any time to perform restorations.
- After one full backup is completed, we will take a snapshot of the previous full backup in the archive repository, but the latest full backup will not be archived.
- Archive backup retention is set to 24 months at default.
- You can also manually specify the period for which the archived data needs to be available in the storage at Retain archived data for field.
- Minimum retention period for archived data is 12 months and maximum is 60 months.
You can select the repository to which the backup archival can be saved. To do so, follow the below steps:
- Click the Active Directory tab.
- Go to Settings -> Backup Settings.
- This page will display all the domains configured. Click the edit icon corresponding to the domain for which the archive repository needs to be selected.
- Select the required repository from the Select Archive Repository dropdown.
Note: If you have more than one Elasticsearch node configured in Database Settings, it is necessary to set up database backup using a shared repository to utilize the archive feature.
Follow the below steps to configure database backup using a shared repository:
- Go to Admin -> Database Settings -> Database Backup.
- Select the Enable Database Backup option.
- Select any of the configured shared repositories from the Repository dropdown.
- You can also specify the Frequency at which the backup needs to run automatically.
- Click Save.
- Restart the product to commit the settings.
Indexing and deindexing
To index and de-index archives, click Show Archives at the top-right corner. The below information is displayed on the page:
- No. of Archives = The total number of backup archives in the archive repository.
- Total Archives Size = Total space occupied by the archived data.
- No. of Indexed Archives = The total number of indexed archives available for performing restorations.
- Indexed Archive Size = Total space occupied by the indexed data.
