VAST Cluster enables you to protect your data with the following backup and recovery features:
Snapshots which enable local backup on the VAST Cluster itself.
In local backup, snapshots are taken periodically and retained on the cluster for a configurable period. Data that was backed up with snapshots can be accessed in a read only virtual directory via a client connection to the protected path. Data can be restored by simply copying from the virtual directory to another directory.
For full feature documentation, see Snapshots and Local Backup.
Backup to S3.
In backup to S3, snapshots (which can also be retained for local backup) are copied to an AWS S3 bucket or a custom target location that is accessible via S3 operations. Backed up data can be accessed in a read only virtual directory via client connection to the root of the cluster's element store. Data can be restored by simply copying from the virtual directory to another directory.
For full feature documentation, see Backup to S3.
Native replication to another VAST Cluster.
In native replication, data is replicated to a path on the replication peer where it is stored in read only format. Snapshots (which can also be retained for local backup) are copied regularly to the peer and retained on the peer for a configurable period.
Native replication enables failover to a native replication peer, in which replicated data becomes writeable and the peer can be used in place of the original cluster.
This feature enables you to create and maintain immutable backups. Snapshots and protection policies can be flagged indestructible and they are then protected from accidental or malicious deletion and modification. Modifying and deleting indestructible policies and snapshots requires a token-based authorized unlocking of an indestructibility mechanism.For full feature documentation, see Keeping Indestructible Backups.
