Managing the Data Protector Internal Database
Maintaining the IDB
Chapter 9 408
Purging Obsolete Filenames
During the purge process, Data Protector automatically checks for and
purges obsolete filenames from the IDB to free up space for new
information. A filename becomes obsolete when there are no file versions
for the filename in the IDB.
Use the Internal Database Purge Preview Report and Internal
Database Purge Report to get more information about the purge. Refer
to “Configuring the Database Reports and Notifications” on page 400.
How to Purge
Obsolete IDB
Filenames Purge the IDB when no other backups are running on the Cell Manager.
Run the following command:
omnidbutil -purge -filenames
You can limit the purge to one or more clients by running the following
command:
omnidbutil -purge -filenames
Data Protector skips purging filenames on the clients that have fewer
than 1,000,000 obsolete filenames. In order to purge filenames on these
clients as well, use the
-force subcommand.
Extending the Database Size
It is required to extend the IDB size for the following reasons:
• The space for the filenames is consumed and another fnames.dat file
is needed.
• More disk space is needed for the detail part of the IDB (file versions
and attributes)
You can extend the size of the IDB in either of two ways:
• By creating new DC (Detail Catalog) directories and, possibly,
locating them on different disks.
• By creating additional fnames.dat files.
Creating New DC Directories
You create a new DC directory using the Internal Database context in
the Data Protector Manager . See Figure 9-3 on page 396. For detailed
steps, refer to the online Help index keyword “creating DC directories”.
