In UltraDNS, a backup is also known as a Snapshot. A zone snapshot represents the state of a zone (i.e. primarily its RRSet configuration) at the time the Snapshot is created.
Performing a zone Restore uses the most recent zone snapshot, and overwrites the zone's current configuration with that of the one stored in the Snapshot. The zone snapshot can be restored at any point in time, as long as the zone meets the required criteria.
Snapshot or Restore are background activities, and as such, it is highly recommended that you refrain from performing any activity that could change the zone configuration while a Snapshot or Restore is in-progress. Doing so might lead to data inconsistency or other unexpected results.
Snapshot Restrictions
-
A zone can have a maximum of one Snapshot at a time. In other words, a zone snapshot request will either create a Snapshot (if it does not already exist), or will overwrite the existing Snapshot (if it already exists).
-
Snapshot and Restore only supports primary zones
-
The zone should not have more than 50,000 records, including the allowed pool's resource records.
-
The zone should not have or include the following:
-
Mail Forwarding records.
-
Signed zones
-
Secondary zones
-
Alias zones
-
Suspended zones
-
To Create a Snapshot:
-
Create a Backup Name for the record backup you are about to create.
-
The Description is an optional field.
-
Click the Create Backup button.
-
Once the backup completes, you will see an entry with the Name you provided, the description (if any), and the date and time the backup was created.
To Restore a Backup:
-
Click the Restore button on an existing backup record.
-
Click the Restore button on the Warning message that states that performing the backup action will overwrite your existing zone state upon completion.
-
Once the Restore completes, your new/old zone details will appear in your account.
To Delete a Snapshot:
It is recommended that you delete any backups that you no longer need.
-
Click the Delete button next to the backup that you want to delete.
-
Click the Delete button again to confirm the deletion of the backup.
