The volume contains 150+ jobs with full backup, delta and incremental backups.

We get a 12-14Gb file each night when an incremental job is run.
The  console log also states that the backup job contains 12-14Gb while the restore job is only showing 800Mb.

Another thing I note is that the backup job says 1561 files, while the restore job says 309.
The restore I run is from "bat" with selection of all files from the last incremental run (job 151).


From the console of the resore job:
  Restore Client:         DVT_backup_server-fd
  Start time:             02-May-2008 15:05:26
  End time:               02-May-2008 15:06:45
  Files Expected:         309
  Files Restored:         309
  Bytes Restored:         817,354,288

From the console of the backup job:
  Job:                    fileserver1.2008-05-01_23.05.40
  Backup Level:           Incremental, since=2008-04-30 23:05:02

Is there something very basic that I have not yet understood?
