Checking the Consistency of the Database

Data Protector by default checks the consistency of the IDB before the
IDB is backed up. This is extremely important for recovering the IDB
and backed up data in case of a disaster.

Additionally, you can manually perform the following IDB checks:

Check of the
core part of
the IDB

Checks the MMDB (Media Management Database)
and CDB (Catalog Database) parts without
information about filenames. It takes approximately
5-10 minutes for a medium size IDB. To perform it, run
the

omnidbcheck -core

command.

Filenames
check

Checks IDB information about filenames. It takes
approximately one hour for a medium size IDB. To
perform it, run the

omnidbcheck -filename

command.

Simple
check of the
DCBF part

Checks if the DC binary files exist and what their size
is. It takes approximately 10-30 seconds for a medium
size IDB. To perform it, run the

omnidbcheck -bf

command.

Complete
check of the
DCBF part

Checks the consistency of media positions and the DC
binary files. It takes approximately 10 minutes for
each GB of the DCBF part. To perform it, run the

omnidbcheck -dc

command.

Check of the
SMBF part

Checks for the presence of session messages binary
files. It takes approximately 5-10 minutes. To perform
it, run the

omnidbcheck -smbf

command.

Check of the
SIBF part

Checks the consistency of object versions and
Serverless Integrations Binary Files. It takes
approximately 10 minutes for each GB of the SIBF
part. To perform it, run the

omnidbcheck -sibf

command.

Quick check

Checks the core part (MMDB and CDB), filenames,
and the DCBF part. It takes approximately two and a
half hours for a medium size IDB. To perform it, run
the

omnidbcheck -quick

command.
