Top Forums UNIX for Advanced & Expert Users Speed problems with tar'ing a 500Gb directory on an eSATA drive Post 302623241 by rbatte1 on Friday 13th of April 2012 10:09:48 AM

Would you consider:-
Code:
# cd source_directory
# tar -cvf - . | rsh target_server "cd target_directory ; tar -xvf -"

I'm assuming it's rsh not remsh for your OS.

If the server is remote or the network is the bottleneck, you could consider:-
Code:
# cd source_directory
# tar -cvf - . | compress | rsh target_server "cd target_directory ; uncompress | tar -xvf -"

Of course, this latter option costs on CPU and is best on multi-proc servers so that the tar and compress are not competing.
I've shovelled 200Gb between remote sites over 2M link in a weekend with something like the above, although the syntax will need to be checked. I must have got pretty good compression I suppose. I can't really test it at the moment.

You will need to ensure that the local server can remote shell to the target. An entry in /.rhosts should suffice, but if this seems a good plan but you can't get remote shell working, let us know.


I hope that this helps

SHTOOL-TARBALL.TMP(1)					      GNU Portable Shell Tool					     SHTOOL-TARBALL.TMP(1)

NAME
shtool-tarball - GNU shtool command for rolling standardized tarballs SYNOPSIS
shtool tarball [-t|--trace] [-v|--verbose] [-o|--output tarball] [-c|--compress prog] [-d|--directory directory] [-u|--user user] [-g|--group group] [-e|--exclude pattern] path [path ...] DESCRIPTION
This command is for rolling input files under path into a distribution tarballs which can be extracted by tar(1). The four important aspects of good open source software tarballs are: (1) unpack into a single top-level directory, (2) top-level directory corresponds to the tarball filename, (3) tarball files should be sorted and (4) arbitrary names for file owner and group. OPTIONS
The following command line options are available. -v, --verbose Display some processing information. -t, --trace Enable the output of the essential shell commands which are executed. -o, --output tarball Output tarball to file tarball. -c, --compress prog Pipe resulting tarball through compression program prog. -d, --directory directory Sets the top-level directory into which the tarball unpacks. By default it is tarball without the trailing ".tar.*" extension. -u, --user user The user (owner) of files and directories in the tarball to user. -g, --group group The group of files and directories in the tarball to group. -e, --exclude pattern Exclude files and directories matching comma-separated list of regex pattern from the tarball. Directories are expanded before the filtering takes place. The default filter pattern is ""CVS,\.cvsignore,\.svn,\.[oa]$"". EXAMPLE
# Makefile.in dist: ... V=`shtool version -d short ...`; shtool tarball -o foobar-$$V.tar.gz -c 'gzip -9' -u bar -g gnu -e 'CVS,.cvsignore' . HISTORY
The GNU shtool tarball command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 1999 for GNU shtool. SEE ALSO
shtool(1), tar(1), compress(1). 18-Jul-2008 shtool 2.0.8 SHTOOL-TARBALL.TMP(1)
