Now the screen displays
Do you want to do volume locking backup (YIN)? (_)
4.
Enter Y if you want to perform Volume locking backup. Volume locking
backup takes advantage of SECURED Volumes which have read and write passwords.
You will be asked to enter the names of n/STAR Volumes to back up. Press
<RETURN> after each Volume name you enter, and press <RETURN> wi thout
making an entry to finish the entry cycle.
When the Tape Backup System actually backs up the Volume, the write password is temporarily changed to prevent users from accessing files in the
Volume while it is being backed up. (If a user has a file opened in the
Volume being backed up, and the Volume is SECURED, that file will not be
backed up. The file name is displayed on your terminal, and- the file is
skipped.)
Enter N if you do not want to perform Volume locking backup.
Either a Y or an N response causes the following message to display:
Enter FP address (for example, FE) to be backed up: _
You can enter an FP ~ddress in hex and press <RETURN>, if you are backing
up a system having multiple File Processors connected by the Molecular
Model Interconnect (MMI). If you just press <RETURN>, the default address
of FF is used. After entering your response, the screen displays:
Do you want to do change-only backup (YIN)?

This option lets you specify that you only want to back up files which
do not have their ARC (archive) bi t set. If the ARC bi t was originally
set (see Step 6 below), it is cleared whenever you modify the file.
Therefore, by selecting this option, you can back up only those files
which have been modified since your last backup.
If you want to use this option, press Y. If you do not want to use this
option, press N. Either response causes the following message to display:
Do you want to set the archive bit (YIN)?

If you answer Y to this question, the ARC bit of each file backed up will
be set. Thereafter, modifying the file will clear the ARC bit, flagging
it for another backup operation. If the file is not modified, and you
answer Y in Step 5, above, that file will not be backed up again until the
ARC bit is cleared by modifying the file.
If you answer N to this question, the ARC bit will not be changed during
the backup process.
