MS Exchange Incremental backup fails when circular logging is enabled.
Incremental backup fails with following error -
Backup setup error for "' '": An incremental backup cannot be performed when circular logging is enabled
There possibly are two causes of this error.
* "Enable circular logging" is enabled
* "Enable circular logging" is disabled but "Microsoft Exchange
Information Store" service wasn't restarted after the option is disabled.
Be sure to restart "Microsoft Exchange Information Store" service after disabling "Enable circular logging" option.
