Air Cleaner User Manual

Directory names must be in one of the following formats:
v /directory/filename
v /directory
v ./filename
v ./directory/filename
v ./directory
All files will be backed up relative to the root (/) directory by
automatically inserting a period (.) at the beginning of each
filename, if it does not already exist. Otherwise, they are
backed up relative to their file system mount point.
4. After confirming the above entries, make sure the backup media is properly
inserted in the drive and press Enter to begin the backup.
Note: If you are backing up to a tape drive, the tape will not be rewound upon
completion of the backup. This enables you to perform additional backups
(also without rewinding), thereby “stacking” the backups onto a single tape.
Understanding Exclude List Processing on Backup Operations
Backup processes use the following rules when processing backup exclude lists:
v If /usr/lpp/sysback/.exclude_list exists, the contents are processed unless
another path and file name are explicitly specified.
v If you have created an exclude list file in an alternate location, specifying its
path and file name with the backup command will cause the backup to process
the content of this file rather than the default. Even if the default
/usr/lpp/sysback/.exclude_list file exists, it will be ignored for this iteration of
the backup command.
v If you have an existing /usr/lpp/sysback/.exclude_list file, but would like to
temporarily override it and exclude nothing, you could do this to avoid deleting
the default exclude list:
root@lasher> touch /tmp/empty.excl
sysback -f /dev/rmt0 -E /tmp/empty.excl
This would cause the backup command to process the contents of the empty file
thereby excluding nothing.
Using SysBack with Fire Walls
SysBack currently opens the following ports by default on each side of a remote
communication with another system:
v 1239
v 1023 for standard out
v 1022 for standard error
If ports 1023 and 1023 are not available, SysBack will decrement this number until
it reaches a port not already. However, SysBack will not use a port number less
than 512. At this time, there is no way to specify which ports SysBack will utilize
and any SysBack remote services between systems separated by a firewall will
require that the needed ports be opened. You must configure the firewall to open
up the ports that the server and clients need. Because fire walls differ in how you
open the ports, you must follow the instructions that accompanied the firewall
software or hardware that you are using. If you need help with opening ports,
please contact the supplier of your firewall.
