Backup Catalogs Are
Missing When You Run Multiple Instances of Ntbackup.exe
and Start Backups at the Same Time

of those backup sets may be missing from the Restore
tab in NTBackup. Although the backups will complete
successfully and without errors, when you try
to restore the backups, one or more of the catalogs
on the Restore tab in NTBackup
is missing. You cannot re-create these missing
catalogs while one of the other backups that was
created at the same time already exists on the
Restore tab. As a result, you cannot restore
all backup sets that exist as backup jobs on a
volume or tape

Not Truncate Active Directory Logs During a System-State
Backup

you create a system-state backup on a domain controller
(DC), the NTDS logs are not cleaned up. The NTDS
logs are being copied from the Edb.log file to
an Edbxxxxx.log file each time backup runs,
but the Edbxxxxx.log files are not deleted.
The log files would normally be deleted by the
circular logging nature of the DS. However, because
some environments do not incur many changes, circular
logging may appear to not work because it takes
a long time to purge these files and disk space
is wasted during this time.
