Restoring full database snapshots in Vertica can be a little tricky due to various constraints. The following are the constraints:
The database must be down. It is good to have another database cluster to serve the application by the time the restore is complete on the primary cluster.
The new cluster should have the same number of hosts as the base cluster of which the backup is created. This constraint is included to tackle K-Safety issues that might arise later. In fact, it is important to keep even node names and the IP addresses the same as that of the nodes in the base cluster.
We can use a full database snapshot created in Vertica 5.0 to restore into a 6.0 database. To begin a full database snapshot restore, log in using the database administrator's account created during installation. We cannot run the utility as root.
