I have setup the following schedule setup in Backup Exec 10d
Monday Full - Backup files Using Archive Bit (reset Archive Bit)

Tue Differential - Back Up changed files since last full - Using archive bit( does not reset archive bit)

Wed Differential - Back Up changed files since last full - Using archive bit( does not reset archive bit)

Thur Differential - Back Up changed files since last full - Using archive bit( does not reset archive bit)

Frid Differential - Back Up changed files since last full - Using archive bit( does not reset archive bit)

Saturday Differential - Back Up changed files since last full - Using archive bit( does not reset archive bit)

Monthly Full - Backup files Using Archive Bit (reset Archive Bit)
I have the option When this job begins - Overwrite Media When I go to the restore tab and try to do a restore, I don't see the Monday date just the differential date of Tuesday. What am I doing wrong?

Create a single selecton list for the FULL job
.
Then create a Backup Job and use that selection list and change the backup method to full and schedule it.

Create another job and use the same selection list above, but change the backup method to DIFF>

The job has to use the same selection list and when the DIFF job runs it will check the files according to the archive bit on the same files the full would backup only backup changed files

A Differential backup backs up only the selected files that have their archive bit set to ON but does not set the archive bit back to OFF. A Differential backup will back up all selected files that are new and changed since the last full backup. The advantage of a Differential comes at restore time; you’ll need only the last full backup and the last differential to get a complete restore. In the case of restoring with Incremental backups, all the Incremental backups since the last full backup plus the last full backup would be necessary.

A very simple two media weekly rotation that takes advantage of new and changed files might go like this:
Media 1: labeled “Week 1 Full”
Media 2: labeled “Daily Differential 1″

Create three backup jobs with the same file selections:
Monday: Full backup, overwrite. Week 1 Full.
Tuesday through Friday : Differential backup, overwrite. Daily Differential.
(If the differential is too large to append to the media, then add an additional media and label it “Daily Differential 2.”)

It is a good idea to have and rotate more than one pair of media sets. Four pairs of media will provide almost a month’s worth of in-depth data protection for most home and small office applications.
