I have recently installed a new 2008 R2 (file) server on our network. It will be replacing the existing 2003 R2 (file) server on which our nightly (full) backups run, using Backup Exec 2010. To help migrate everything, I enabled FRS to replicate our 2 big shares, that all users use for file storage. Our nightly backup was running around 112G-115G nightly, and we've prety much never had a hiccup. Well, since starting up the file replication (Tuesday night), the last 2 nights' backups only backed up 23G worth of data, and there are no errors at all: Backup Exec, apparently, thinks its run a regular full backup! Absolutely NO changes were made to the backup software (or any software, for that matter).
Does anyone have any idea what the heck is going on? I'm currently scouring the knowledgebase at Symantec to find a resolution, but figured I would throw it out here, to see if I can get some help. Thanks.
