BACKUP

You can use wildcards to back up all ﬁles of a particular name or type, or to back up

all ﬁles (*.*), which is the default.

Examples

1. The following command illustrates the use of wildcards when backing up ﬁles:

.BACKUP DL0:F*.FOR,*.MAC,T*.SAV DU1:WRK

Mount output volume in DU1:; Continue? Y

?BUP-W-Not a BACKUP volume DU1:

DU1:/BUP Initialize; Are you sure? Y

?BUP-I-Bad block scan started

?BUP-I-No bad blocks detected

?BUP-I-Creating output volume 1

Files backed up:

DL0:FUNC1.FOR

DL0:FUNC2.FOR

DL0:PROG1.MAC

DL0:PROG2.MAC

DL0:DEMO.MAC

DL0:KMON.MAC

DL0:TEST.SAV

?BUP-I-Backup operation is complete

2. The next command illustrates backing up a logical-disk ﬁle into a saveset. This

command stores the logical disk SAVE.DSK in the saveset OLDWRK.BUP on

device DU1:

.BACKUP DL0:SAVE.DSK DU1:OLDWRK

An advantage of backing up logical disks as individual ﬁles is that it can be

convenient to save several logical disks in one saveset. A disadvantage is that

you cannot access (get a directory listing or restore) individual ﬁles in each logical

disk stored this way.

Figure 1 illustrates this way of backing up logical disks.
