Setting the retention time for a file explicitly

You can set the retention time for a file explicitly by modifying its last access time. You can use any suitable command or program over NFS or CIFS to modify the last access time.

About this task

After a file has been committed to WORM, you can extend but not shorten the retention time. The retention time is stored in the atime field for the file.

Note: You cannot explicitly set the retention time of a file to infinite. That value is only available when you use the default retention period to calculate the retention time.

Procedure

Use a suitable command or program to modify the last access time for the file whose retention time you want to set.
In a UNIX shell, use the following command to set a retention time of 21 November 2020 6:00 a.m. on a file named document.txt:
touch -a -t 202011210600 document.txt
Note: You can use any suitable command or program to modify the last access time in Windows.
