That's crazy. Try this:

ssh fileserver 'tar cMf /tapedrive /file'

If you want tar to work with multiple volumes it must know that it is writing to a tape drive. At least the stardard tar does, you seem to be gnu's tar, which I have never used.

In a later post you say "I tried to mount my files". I sure hope so. tar isn't going to work with an unmounted filesystem. Are you trying to remote mount them via nfs? If so, when you export them or share them you must explicitly allow root access otherwise root will be mapped to nobody.

NAME
bf_tar - shell script to write a tar file of a bogofilter directory to stdout SYNOPSIS
bf_tar [-r] [-R] bogofilter_directory DESCRIPTION
bf_tar bundles a bogofilter working directory in tar format and copies it to standard output (your console, or where you redirect it, see EXAMPLES below). OPTIONS
The -r option causes bf_tar to remove inactive log files after the archive has been written successfully. The default is to leave log files. The -R option causes bf_tar to remove inactive log files before the archive is written. This may reduce chances that the resulting archive is recoverable should it become damaged. The archive may be smaller though. The default is to leave log files. EXIT STATUS
The script exits with status code 0 if everything went well, and nonzero if it encountered trouble. EXAMPLES
o bf_tar ~/.bogofilter > outfile.tar Writes a standard .tar file containing the essential files from ~/.bogofilter to outfile.tar. o bf_tar ~/.bogofilter | gzip -9 -c > outfile.tar.gz Writes a gzipped .tar.gz file containing the essential files from ~/.bogofilter to outfile.tar.gz. o bf_tar `pwd`/mydirectory > outfile.tar Prepend $(pwd)/ or `pwd`/ if you want to specify an absolute path instead of a relative path. NOTES
This script is meant for use with Berkeley DB based bogofilter versions. This script requires a SUSv2 compliant pax utility. This script expects a SUSv2 compliant shell. Solaris systems should have the SUNWxcu4 package installed (when bogofilter is configured) so that /usr/xpg4/bin/sh can be used. 07/23/2007 BF_TAR(1)
