Backups can take a long time to carry out. You can shorten the time it takes to do a complete backup by using the CHANGE-FILE command to exclude accounts and files whose data rarely changes and for which you already have adequate backups.
To exclude an account from all backups, put DX (or DCX) in Attribute 1 of the Account Definition item in the SYSTEM Dictionary that points to the account.
To exclude a file, put DX (or DCX) in Attribute 1 of the Master Dictionary item.
To save a file but not its data, put DY (or DCY) in Attribute 1 of the Master Dictionary item.

NOTE |
All other users must be logged off before you DX accounts or files, since the SYSTEM Dictionary is altered by this procedure. |

CAUTION |
Be careful when using a selective backup medium to restore data on the disk drive. When restoring data from a selective backup medium, its contents overwrite the data on disk. This means that any accounts or files on disk which were not saved on the selective backup medium are permanently lost. |
