Using Run Options in a Backup Command
Backing Up Only Changed Files
Use the PARTIAL option to back up only files that have been modified since a given
date and time. Enter PARTIAL followed by the date (that is, the first three letters of the
month, the day of the month, and the year, with spaces separating them), a comma, and
the time (using a 24-hour clock).
For example, this command backs up all files in the system that were modified after 6
p.m. on January 24, 1999:
If you regularly back up your files, you can use the PARTIAL option to save tape space
and backup time. Each time you back up files, use the PARTIAL option to specify the
date and time of the previous backup. This lets you maintain current backup copies of all
your files without copying files that are already backed up.
