Changing the retention profile for a file system

The file system must be unmounted when you make changes to the retention profile. After unmounting

the file system, click Modify on the WORM/Data Retention panel to open the Modify WORM/Data

Retention dialog box and then make your changes.

To change the configuration from the CLI, use the following command:

ibrix_fs -W -f FSNAME -o "retenMode=<mode>,retenDefPeriod=<period>,retenMinPeriod=<period>,

retenMaxPeriod=<period>,retenAutoCommitPeriod=<period>"

Managing WORM and retained files

You can change a file to the WORM or WORM-retained state, view the retention information

associated with a file, and use administrative tools to manage individual files, including setting or

removing a legal hold, setting or removing a retention period, and administratively deleting a file.

Creating WORM and WORM-retained files

The autocommit and default retention periods determine the steps you will need to take.

Autocommit period is set and default retention period is zero seconds:

• To make a WORM file retained, set the atime to a time in the future.

Autocommit period is set and default retention period is non-zero:

• Files remaining unchanged during the autocommit period automatically become

WORM-retained and use the default retention period. You can assign a different retention

period to a file if necessary.

Autocommit period is not set and default retention period is zero seconds:

• To create a WORM file, run a command to make the file read-only.

• To make a WORM file retained, set the atime to a time in the future.

Auto commit period is not set and default retention period is non-zero:

• To create a WORM-retained file, run a command to make the file read-only. By default, the

file uses the default retention period.

• To assign a different retention period to the WORM-retained file, set the atime to a time in

the future.

NOTE: If you are not using autocommit, files must explicitly be made read-only. Typically, you

can configure your application to do this.

Making a file read-only

Linux. Use chmod to make the file read-only. For example:

chmod 444 myfile.txt

Windows. Use the attrib command to make the file read-only:

C:\> attrib +r myfile.txt

Setting the atime

Linux. Use a command such as touch to set the access time to the future:

touch -a -d "30 minutes" myfile.txt
