Since the data in durable workspace volumes is not automatically written back to the Domino File System, users can lose work if the volume is lost or deleted. When Domino is running on AWS, it safeguards against this by backing up the EBS volume that backs up the workspace PV with EBS snapshotting to S3.
EBS snapshots can be expensive, especially if you have a lot of users. To manage snapshots for your organization, please reach out to Domino Support.
If you accidentally deleted or lost a durable workspace volume that contains data you want to recover, contact Domino Support for assistance in restoring from the snapshot.
