Hi Remco,

Judging from these similar posts...


http://social.technet.microsoft.com/Forums/exchange/en-US/3736df82-e5cb-4665-a97c-eb4a70868271/information-store-database-buffer-paged-during-backup?forum=exchangesvravailabilityandisasterrecoverylegacy

... it looks like it could be related to activity that the
Exchange Server does during a backup.

It also looks like it's a general backup issue since the same
problem appears with Windows Server Backup as well.

The second link above showed that increasing the page file size helped.


Thank you,
