Primary use case is covering fast backup and restore for customers, mostly for SQL databases, some Oracle database systems in servers, and some file share backups with Snapshots with the possibility of restore.
SnapCenter is usually an additional software, which is not the main backup software. Most companies have already found a backup solution and are using SnapCenter to be able to do a fast restoration of their data. Therefore, they are using two solutions at once, side-by-side. Companies will have their primary backup solution and SnapCenter as a redundancy because the primary solution isn't favored to recover data so quickly.
