Mksysb for linux
Aix is a unix based os developed by IBM and was originally released in the mid 80s for PC RT. When IBM released the RS/6000 in 1992, it released AIX 3.1 and built in is a mksysb script to do a full rootvg or OS backup. Other volume groups are not touched by this script. It was aimed at scsi tape drives. When booted from tape, the system would be restore rootvg to exactly what it contained when it was backed up. When finished, the system reboots. IBM never supported writing to cd but went directly to dvd. A mksysb can be written to dvd and then booted and restored from dvd. This function would be VERY helpful to linux releases or unix released. What was described earlier is simillar to a product in AIX called Network Install Manager - nim. Using nim, a root user can do a bootable backup to a remote system and then restore from that system. A nim restore is the fastest form of installing AIX and is used by manufacturing to preload systems. Today, at AIX 6.1, nim and mksysb are mature and trusted processes. Non rootvg volume groups are backed up using savevg. savevg is better than tar as it creates logical volumes the correct size and correctly names the mount points and then restores the data. Again, its a mature process. Even open files are backed up with mksysb and savevg although any save to the file after its backed up isn't reflected. A mksysb has 3 components, A boot image, a complete list of files and the actual backup. When the mksysb is taken, it compares what is on the list to what is on the tape in the backup. They must agree. Again, the same for linux would be helpful. I am looking for one for an OS backup of Fedora Core 9 or 10. I believe the linux developers like Red Hat or SUSE or Debian, are best equipped to create such a backup program as they best know their own OS.

2. Linux
Hi all...
In my Unix system a program exists called "daemon2" which is responsible to enqueue program executions. For example, if I want to make the system to enqueue lpr executions for certain users, I call daemon2 with lpr as the parameter.
Is there an equivalent in Linux?
Thanks

Hi Guys,
Does hp-ux has mksysb equivalent with aix? Or something similar that you can save the system config.
Or you just backup the boot image, that's it.

backup_volinfo
BACKUP_VOLINFO(8) AFS Command Reference BACKUP_VOLINFO(8)
NAME
backup_volinfo - Displays a volume's dump history from the Backup Database
SYNOPSIS
backup volinfo -volume <volume name> [-localauth]
[-cell <cell name>] [-help]
backup voli -v <volume name>
[-l] [-c <cell name>] [-h]
DESCRIPTION
The backup volinfo command displays a dump history of the specified volume, reporting information such as the date on which the volume was
dumped and the tapes that contain it. Include the ".backup" extension on the volume name if the backup version of the volume was dumped.
OPTIONS
-volume <volume name>
Names the volume for which to display the dump history. Include the ".backup" or ".readonly" extension if the backup or read-only
version of the volume was dumped.
-localauth
Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. The backup command interpreter presents it to
the Backup Server, Volume Server and VL Server during mutual authentication. Do not combine this flag with the -cell argument. For more
details, see backup(8).
-cell <cell name>
Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see backup(8).
-help
Prints the online help for this command. All other valid options are ignored.
OUTPUT
The output includes a line for each Backup Database dump record that mentions the specified volume, order from most to least recent. The
output for each record appears in a table with six columns:
dumpID
The dump ID of the dump that includes the volume.
lvl The depth in the dump hierarchy of the dump level at which the volume was dumped. A value of 0 indicates a full dump. A value of 1 or
greater indicates an incremental dump made at the specified depth in the dump hierarchy.
parentid
The dump ID of the dump's parent dump. A value of 0 indicates a full dump, which has no parent; in this case, the value in the "lvl"
column is also 0.
creation date
The date and time at which the Backup System started the dump operation that created the dump.
clone date
For a backup or read-only volume, the time at which it was cloned from its read/write source. For a read/write volume, the same as the
value in the "creation date" field.
tape name
The name of the tape containing the dump: either the permanent tape name, or an AFS tape name in the format
volume_set_name.dump_level_name.tape_index where volume_set_name is the name of the volume set associated with the initial dump in the
dump set of which this tape is a part; dump_level_name is the name of the dump level at which the initial dump was backed up;
tape_index is the ordinal of the tape in the dump set. Either type of name can be followed by a dump ID in parentheses; if it appears,
it is the dump ID of the initial dump in the dump set to which this appended dump belongs.
EXAMPLES
The following example shows part of the dump history of the Backup volume "user.smith.backup":
% backup volinfo -volume user.smith.backup
DumpID lvl parentID creation date clone date tape name
924600000 1 924427600 04/20/1999 05:20 04/20/1999 05:01 user_incr_2 (924514392)
924514392 1 924427600 04/19/1999 05:33 04/19/1999 05:08 user_incr_2
924427600 0 0 04/18/1999 05:26 04/18/1999 04:58 user_full_6
