Can I run concurrent backups of multiple read only filegroups? I have 62 readonly filegroups in a SQL server 2008 enterprise database. Can I backup multiple read only filegroups at the same time? I would assume this to be the case but given this database is over 20TB in size I do not want to invalidate any files by giving it the ol' college try.
Yes you can do multiple full file-group backups concurrently. The primary concern I would have would be for disk I/O and network I/O throughput doing so many at once. They'll still complete, just all slowly. Unless you have the I/O to handle 20TB at once.
