necessary to specify a the hostname of a remote system not
listed in the device selector dialog screen. This is useful when
initiating a Pull Backup.
Device name The device, if a tape drive or virtual device was selected. You
may edit this field as necessary to specify a device on a remote
system not listed in the device selector dialog screen. This is
useful when initiating a Pull Backup.
Images directory
The directory name, if previously selected. You cannot change
this field from this screen.
Backup file ID
Default=date/time (MMDDhhmm). Uniquely identifies the
backup. You can change this field to any value but it cannot
contain single (’) or double (″) quotes. This field is active only
when you back up to a disk image file.
Dynamically Created Backup File ID
Generates a dynamic backup file ID. This option uses the same
current date and time values at the time of command execution
as the ID. If a dynamic backup file ID already exists and this
option is set to “yes”, the existing ID is overwritten.
Report output type
Default=progress indicator. Keep the default value if you want
to display a progress indicator during the backup process,
which indicates the approximate total backup time and amount
completed. Press Tab to select “file list” if you want to display
a list of files as they are being backed up, or Tab once more to
show “only errors” that occur during the backup.
Compress data before writing to media?
Default=“no” for tapes and “yes” for disk image backups. Press
Tab to change the option. “yes” indicates that the data will be
compressed before it is written to the backup media.
Compressing the data usually increases backup performance
and uses between 25 and 40% less space on the media. For best
performance, do not select this option if the backup device
provides its own hardware data compression. Compressing
with software data uses considerably more CPU cycles to
process the data.
Incremental backup level (0=full)
Default=(Blank/None). To perform an incremental backup of
the volume group, enter an incremental level. Level 0 indicates
a backup of all files and logical volumes. Leaving this field
blank also backs up all files and logical volumes but the
previous level 0 incremental backup information, if any, is not
overwritten. Refer to “Understanding Incremental Backups” on
page 4-1 for additional details.
Include non-JFS logical volumes?
Default=yes. To exclude all non-journaled file systems (raw
logical volumes) from the backup, press Tab to change the
value to “no”. If you select “no” to this option, all raw logical
volume data is excluded from the backup, but the logical
volumes can be recreated using the LVM information on the
