Ray,
What is the XferMethod and backup schedule (ie, how often do you do
incrementals and fulls)? Which backup are you viewing (ie, how many
incrementals need to be merged to view it)? Are you running v3 or v4?
Two options are to:
- use BackupPC_ls so you can see the backup tree using the command line
- look in the XferLOG files to figure out which files are in which
backup.
