You'll need to "fast forward" past the tar backup (I do this on Solaris so I can't guarentee the commands I'm offering here will help, but maybe the concepts will help you find the proper commands on your OS):

mt -f /dev/rmt/0n fsf 1

On Sun, the 0n device is the first tape but it's the "no rewind device" so mt will forward to the first block past the EOF and not rewind the tape (this is important). You can change the last number if you want to back up a third block of data.

Next use the backup command to back up the data. If you have another file system to back up, you can continue past the vdump backup as long as you use a "no rewind device" for vdump. Otherwise you'll have to jump past two backup blocks:

mt -f /dev/rmt/0n fsf 2

To restore from the second backup on the tape, you use the same mt command to get past the first EOF block to the vdump backup and then restore it.

Hope that helps as I don't know what vdump is. You can also pick up O'Reilly's backup and recovery book. Excellent book.

Hi,


first of all use:
ufsdump 0ucf /dev/rmt/0hbn /
this comand to do the backup for any file system ( here we do for root). notice the following
h : stands for high density tape
b: block
n: no rewind
0: the name of drive 1 or 2 or 3 as you defind it


second use :
tar cvf /rmt/0hbn /dataaa (dataaa is your data that you want to back it up).

NAME
smbtar - shell script for backing up SMB/CIFS shares directly to UNIX tape drives SYNOPSIS
smbtar [-r] [-i] [-a] [-v] {-s server} [-p password] [-x services] [-X] [-N filename] [-b blocksize] [-d directory] [-l loglevel] [-u user] [-t tape] {filenames} DESCRIPTION
This tool is part of the samba(7) suite. smbtar is a very small shell script on top of smbclient(1) which dumps SMB shares directly to tape. OPTIONS
-s server The SMB/CIFS server that the share resides upon. -x service The share name on the server to connect to. The default is "backup". -X Exclude mode. Exclude filenames... from tar create or restore. -d directory Change to initial directory before restoring / backing up files. -v Verbose mode. -p password The password to use to access a share. Default: none -u user The user id to connect as. Default: UNIX login name. -a Reset DOS archive bit mode to indicate file has been archived. -t tape Tape device. May be regular file or tape device. Default: $TAPE environmental variable; if not set, a file called tar.out. -b blocksize Blocking factor. Defaults to 20. See tar(1) for a fuller explanation. -N filename Backup only files newer than filename. Could be used (for example) on a log file to implement incremental backups. -i Incremental mode; tar files are only backed up if they have the archive bit set. The archive bit is reset after each file is read. -r Restore. Files are restored to the share from the tar file. -l log level Log (debug) level. Corresponds to the -d flag of smbclient(1). ENVIRONMENT VARIABLES
The $TAPE variable specifies the default tape device to write to. May be overridden with the -t option. BUGS
The smbtar script has different options from ordinary tar and from smbclient's tar command. CAVEATS
Sites that are more careful about security may not like the way the script handles PC passwords. Backup and restore work on entire shares; should work on file lists. smbtar works best with GNU tar and may not work well with other versions. DIAGNOSTICS
See the DIAGNOSTICS section for the smbclient(1) command. VERSION
This man page is correct for version 3 of the Samba suite. SEE ALSO
smbd(8), smbclient(1), smb.conf(5). AUTHOR
The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open Source project similar to the way the Linux kernel is developed. Ricky Poulten wrote the tar extension and this man page. The smbtar script was heavily rewritten and improved by Martin Kraemer. Many thanks to everyone who suggested extensions, improvements, bug fixes, etc. The man page sources were converted to YODL format (another excellent piece of Open Source software, available at ftp://ftp.icce.rug.nl/pub/unix/) and updated for the Samba 2.0 release by Jeremy Allison. The conversion to DocBook for Samba 2.2 was done by Gerald Carter. The conversion to DocBook XML 4.2 for Samba 3.0 was done by Alexander Bokovoy. Samba 4.0 06/17/2014 SMBTAR(1)
