One of the most critical situations a Data protector Admin can find themselves in is the loss of the Internal Database, The Database can become unavaiable due to a number of influences such as internal corruption, disk failure or the unintended consequence of updates.
One of the fastest ways to recover the internal database is through the Offline restore.
The benifit of the offline restore over the online restore is that the offline resore will recover the database to the original default location while the online restore requires a new DB80 location.
to run the offline restore you first need to dump the variables to a text file
for example
omniofflr -idb -autorecover -skiprestore -save C:/tmp/offlr_options.txt
this command picks up the variables taken from the Obrindex.dats latest entry and build the .txt file
then running
omniofflr -idb -force -read c:/offr_options.txt
will run the offline restore with the given variables.
I recommend testing the utility on a test server with DP installed to become familair with the process.
additionally you can make a copy of the Obrindex.dat to an alternate location such as a USB or Network share.
Good idea to insure against a disk faiilure and loss of the obrindex,dat
to make a copy set the location of the obrindex.dat file
Default:
C:\ProgramData\OmniBack\Config\Server\Options
To set the alternate location, set the following Global option:
# RecoveryIndexDir=FullPathToTheBackupDir.
Then whenever you run an IDB backup it will automatically write to the alternate location as well as the default and append each IB backup to the both locations.
should you experience a disk failure you would reinstall DP, replace the OBrindex,dat to the default location and run the omniofflr s shown above.
