.SH NAME
smbtar \- shell script for backing up SMB/CIFS shares directly to UNIX tape drives
.SH "SYNOPSIS"
.nf
\fBsmbtar\fR [-r] [-i] [-a] [-v] {-s server} [-p password] [-x services] [-X] [-N filename]
[-b blocksize] [-d directory] [-l loglevel] [-u user] [-t tape] {filenames}
.fi
.SH "DESCRIPTION"
.PP
This tool is part of the \fBSamba\fR(7) suite\&.
.PP
\fBsmbtar\fR is a very small shell script on top of \fBsmbclient\fR(1) which dumps SMB shares directly to tape\&.
.SH "OPTIONS"
.TP
-s server
The SMB/CIFS server that the share resides upon\&.
.TP
-x service
The share name on the server to connect to\&. The default is "backup"\&.
.TP
-X
Exclude mode\&. Exclude filenames\&.\&.\&. from tar create or restore\&.
.TP
-d directory
Change to initial \fIdirectory \fR before restoring / backing up files\&.
.TP
-v
Verbose mode\&.
.TP
-p password
The password to use to access a share\&. Default: none
.TP
-u user
The user id to connect as\&. Default: UNIX login name\&.
.TP
-a
Reset DOS archive bit mode to indicate file has been archived\&.
.TP
-t tape
Tape device\&. May be regular file or tape device\&. Default: \fI$TAPE\fR environmental variable; if not set, a file called \fItar\&.out \fR\&.
.TP
-b blocksize
Blocking factor\&. Defaults to 20\&. See \fBtar(1)\fR for a fuller explanation\&.
.TP
-N filename
Backup only files newer than filename\&. Could be used (for example) on a log file to implement incremental backups\&.
.TP
-i
Incremental mode; tar files are only backed up if they have the archive bit set\&. The archive bit is reset after each file is read\&.
.TP
-r
Restore\&. Files are restored to the share from the tar file\&.
.TP
-l log level
Log (debug) level\&. Corresponds to the \fI-d\fR flag of \fBsmbclient\fR(1)\&.
.SH "ENVIRONMENT VARIABLES"
.PP
The \fI$TAPE\fR variable specifies the default tape device to write to\&. May be overridden with the -t option\&.
.SH "BUGS"
.PP
The \fBsmbtar\fR script has different options from ordinary tar and from smbclient's tar command\&.
.SH "CAVEATS"
.PP
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\&.
.SH "DIAGNOSTICS"
.PP
See the \fBDIAGNOSTICS\fR section for the \fBsmbclient\fR(1) command\&.
.SH "VERSION"
.PP
This man page is correct for version 3\&.0 of the Samba suite\&.
.SH "SEE ALSO"
.PP
\fBsmbd\fR(8), \fBsmbclient\fR(1), \fBsmb.conf\fR(5)\&.
.SH "AUTHOR"
.PP
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\&.
.PP
Ricky Poulten wrote the tar extension and this man page\&. The \fBsmbtar\fR 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\&.
