Hi,
When doing tar -xvf to untar, some tar versions display the blocksize:

I'm trying to tar a bunch of files off to a tape, but for one specific file (it is fairly large, roughly 10Gb) I get the error:
too large to archive
Does tar have a limit of the size of file it can write off to tape? I'm using SunOS 5.8.
Thanks!

SMBTAR(1) User Commands SMBTAR(1)
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Reset DOS archive bit mode to indicate file has been archived.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.
