BACKUP
1. Listing a directory of savesets on a backup volume
You use the same command format to get backup volume directories on
magtapes as on disks or diskettes. However, for certain magtape devices,
this process can take some time. This is because BUP must read to the
logical end of magtape volumes before completing a directory listing.
The directory structure of savesets on backup disks, diskettes, and magtapes
is different from the standard RT–11 directory structure. In addition, a
saveset directory on a magtape is different from that of one on a disk or
diskette.
To display a backup volume directory, first mount the backup volume that
contains either the entire saveset or the first section of a multivolume saveset.
Then issue the BACKUP/DIRECTORY command.
Examples
a. In this example, the directory listing is of the backup volume in device
DU1. The backup volume is a diskette whose backup directory shows
that the volume is the first one in a series of five diskette backups that
contains three savesets:

The saveset file name identifies a saveset section.
If more than one saveset is on a volume, each one on that volume is
listed. In this case, there are three savesets.
2
A section of a saveset is the amount of the saveset that fits on one
backup volume. This means that the number of sections in a saveset
is the same as the number of volumes used to back up a disk.
The section number in a saveset directory indicates what section of a
saveset is on that volume. Disk and diskette directories have a second
number following the section number and separated from it by a slash.
This second number is not on magtape saveset directories.
