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 http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_27697281.html ... 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.
