The default is "backup"\&. .RE .PP \-X .RS 4 Exclude mode\&. Exclude filenames\&.\&.\&. from tar create or restore\&. .RE .PP \-d directory .RS 4 Change to initial \fIdirectory \fR before restoring / backing up files\&. .RE .PP \-v .RS 4 Verbose mode\&. .RE .PP \-p password .RS 4 The password to use to access a share\&. Default: none .RE .PP \-u user .RS 4 The user id to connect as\&. Default: UNIX login name\&. .RE .PP \-a .RS 4 Reset DOS archive bit mode to indicate file has been archived\&. .RE .PP \-t tape .RS 4 Tape device\&. May be regular file or tape device\&. Default: \fI$TAPE\fR environmental variable; if not set, a file called tar\&.out\&. .RE .PP \-b blocksize .RS 4 Blocking factor\&. Defaults to 20\&. See tar(1) for a fuller explanation\&. .RE .PP \-N filename .RS 4 Backup only files newer than filename\&. Could be used (for example) on a log file to implement incremental backups\&. .RE .PP \-i .RS 4 Incremental mode; tar files are only backed up if they have the archive bit set\&. The archive bit is reset after each file is read\&. .RE .PP \-r .RS 4 Restore\&. Files are restored to the share from the tar file\&. .RE .PP \-l log level .RS 4 Log (debug) level\&. Corresponds to the \fI\-d\fR flag of \fBsmbclient\fR(1)\&. .RE .SH "ENVIRONMENT VARIABLES" .PP The \fI$TAPE\fR variable specifies the default tape device to write to\&. May be overridden with the \-t option\&. .SH "BUGS" .PP The smbtar script has different options from ordinary tar and from smbclient\*(Aqs 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 \fIDIAGNOSTICS\fR section for the \fBsmbclient\fR(1) command\&. .SH "VERSION" .PP This man page is part of version 4\&.21\&.2 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 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\&.
