Skipping Files for Backup

On Windows, you can skip files that you do not need to replicate. On Windows, skipping files for backup is enabled by default.

If you keep the default setting of skipping files and you are using a proxy MediaAgent computer to run the scan operation, use the Change Journal option instead of the Optimized Scan (default setting) option.

Use the following registry key to disable skipping files:

[HKEY_LOCAL_MACHINE\SOFTWARE\CommVault Systems\Galaxy\Instance001\iDataAgent\bLREPDisableFilter]

To skip files for replication, set the following registry keys:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\BackupRestore\FilesNotToBackup]

This key contains certain standard files that do not need to be backed up like the page file.

More user specific files can be added here by setting the registry key CV_SKIPDATA (REG_MULT_STR)and listing the directory and files names.

Follow these rules to set up the CV_SKIPDATA (REG_MULT_STR)registry key:

1. Define regular expressions at one level, not recursively.

2. Define full file paths only.

3. Define full directory paths.

Given the following structure:

. :abc.txt dir1 song2.dll song.dll
 ./dir1: aria2.dll aria.dll def.txt dir2
 ./dir1/dir2: song3.dll song4.dll

the following examples refer to the rules described above, respectively.

If you want to skip all .dll files, then the specification of the registry key is as follows:

/filter/*.dll
 /filter/dir1/*.dll
 /filter/dir1/dir2/*.dll

To skip a particular file, the specification of the registry key is as follows:

 /filter/abc.txt
 /filter/dir1/def.txt

To skip a particular folder, the specification of the registry key is as follows:

/filter/dir1/dir2
 /filter/dir1

The last specification skips dir1 and all its contents, so dir2 is also skipped.

Throttling

Throttling parameters set on the IntelliSnap side are not honored for OSDP 7-Mode or OSDP C-Mode.

Throttling can be achieved with OCUM, by setting the maxactivedatatransfer option. Please refer to NetApp’s documentation on OnCommand Unified Manager to see how this option is set.

Deleting or Reassociating a Subclient to a Different Storage Policy

Run a successful workflow job just before deleting or reassociating a subclient to a different storage policy. This ensures that:

• Subsequent jobs run after the configuration change, either run from the workflow or run from the subclient, succeed.

• For 7-Mode only: the dataset corresponding to the storage policy on the OCUM end is conformant.
