Problem With Backup Tapes

[d3aths3rver]

Hi guys
This is my first post and I was hoping someone would help me out.
Im running SBS 2008 for my client, this is their mail server, they are in a domain environment.
Their problem is when they backup. We are running backup executive 12.5 and their tape drive is a HP storageworks DAT 160,
The backups work fine (they are set to run at night), but when they put the tape in the next morning it ejects once during the day at random times always, no matter what. Ive checked the eventvwr but nothing is coming up on that, any ideas on how to solve this, is there a setting somewhere? it ejects fine in the morning it just ejects once again during the day and m getting complaints about this.
Any Ideas???

It may sound like a silly question, but is the backup actually finished in the morning when the tape is ejected? If the backup has filled up the tape, it will eject it and ask for another. So it could be filling the first tape and then continuing onto the next tape and ejecting it when the backup is finally complete.

Hi Matt,

Sorry for the extremely late reply, yes the backup is completed in the morning, the tape ejects once completed. When my client comes into the office, they put in the next night's backup tape scheduled for 10pm the following night. I want to stress that all backup tapes are finishing their jobs.
Simply put - when the next night's backup tape is put in the SCSI tape drive (last night's completed backup ejected new backup tape put in for the next night) The tape drive will spit out the tape during the day. The event logs show no record correlating with the time that the drive spat the next night's tape out. I have been sitting at the server when it has done this for my monthly visit.

There is still plenty of space on the tape before compression, (so it is not the tape itself finishing the job off, by requesting another), and it is happening every day - without fail. But not at the same specific time. - any time of the day.

any more ideas?
