You can configure LiteSpeed to only back up databases that match the specified pattern. Using wildcard and regular expressions is particularly helpful when there are databases with similar names on the same instance or on multiple instances.
Tips:
You can use wildcard characters '?' and '*' to select databases you want to back up. For example, "litespeed*" will include all databases that start with "litespeed" or "LiteSpeed".
Using regular expressions can provide you with more flexibility when selecting databases. For example, the following expressions will include a database if its name:
Begins with "LiteSpeed".
^LiteSpeed
Ends with "_PUBLISHER".
_PUBLISHER$
Begins with "LiteSpeed" followed by digits.
^LiteSpeed\d+
Contains any number within the range 828500 to 828549.
8285[0-4][0-9]
Begins with "LiteSpeed" or "Quest", except "QuestSoftwareCMSS".
^(?!QuestSoftwareCMSS)(Quest|LiteSpeed)
