The above URL showed 3 methods, but, went for the second.

It can be done using mpack tools to work with MIME files. This packet is included into Debian:

# apt-get install mpack

For other Linux systems you can try to user RPM from ALT Linux: ftp://ftp.pbone.net/mirror/ftp.altlinux.ru/pub/distributions/ALTLinux/Sisyphus/files/i586/RPMS/mpack-1.6-alt1.i586.rpm

or compile mpack from the sources: http://ftp.andrew.cmu.edu/pub/mpack/.

– Create an empty directory to extract the back up file:

# mkdir recover
# cd recover
and copy backup into it.By default Plesk backup is gzipped (if not, use cat), so run zcat to pass data to munpack to extract content of directories from the backup file:

# zcat DUMP_FILE.gz > DUMP_FILE
# cat DUMP_FILE | munpack
In result you get the set of tar and sql files that contain domains’ directories and databases. Untar the needed directory. For example if you need to restore the httpdocs folder for the DOMAIN.TLD domain:

# tar xvf DOMAIN.TLD.htdocs

NOTE: ‘munpack’ utility may not work with files greater then 2Gb and during dump extracting you may receive the error like

# cat DUMP_FILE | munpack
DOMAIN.TLD.httpdocs (application/octet-stream)
File size limit exceeded

In this case try the next way below.
