[QUOTE=methyl;302622215]I don't think that tar or cp are the right commands.
To make a straight copy to another mounted filesystem and preserve permissions:
Code:
cd /filesystem_to_copy
find . -xdev -print | cpio -pdumv /new_filesystem
Ps. I have never used tar to back up anything. It is sometimes useful for moving files to alien systems.
Thanks for the input, but the goal is to move the 500Gb of data from the external drive to an offsite compute cluster. I believe the only way I can do this is ftp, and ftp only supports moving single files, not directories. GUIs like Filezilla don't work as they prompt for a new password every time the token-generated one expires.
I don't think it's possible to mount the external hard drive from a cluster that's behind a firewall - I can only connect to the cluster, not from it

Sorry, I don't know how to precisely answer that question! I know I can (if I had enough internal hard drive space) "cp -r" all the data down the SATA cable in a few hours without any issues. It certainly seems I/O on the external drive is the bottleneck with tar. Hopefully this is at the external disk end and not the mobo bus end. Hopefully (I'll find out next week) doing it on a 4-drive RAID0 will overcome that!

However I have seen a modern tar (i.e. one which can deal with files larger than 2Gb) crawl when it demands more memory.
My linux box has 16Gb RAM, but whilst doing this system usage didn't exceed 3Gb (including running the O/S and everything else).
I'm trying to tar a bunch of files off to a tape, but for one specific file (it is fairly large, roughly 10Gb) I get the error:
too large to archive
Does tar have a limit of the size of file it can write off to tape? I'm using SunOS 5.8.
Thanks!

If I have a directory /directory1 and want to tar and zip everything in it into a file new_tar.tar.gz on disk (not tape)
How can I do it?
I tried tar -cv /new_tar.tar /directory1/*

Recently we brought up a Spectralogic 2K Tape Library that had been out of service for about 3 years to replace a DDS-4 tape drive unit as our main backup device.
Everything seemed to go fine but now I have run into a little problem.

Hi,
How do I tar all but a specific set of files in a directory? Is it possible to use regular expressions in the tar command? I want to tar all files except those beginning with D. I tried this
tar -cvf files.tar ^

Thanks (2 Replies)

Hi all. I was able to set up an IBM Ultrium LTO 4 tape drive to use iSCSI (using open-iscsi drivers) to communicate with Red Hat, but it's going really slow, maxing out in tar and dd tests at like 16 MB/s (using a block size of 128k). The thing is rated for 30MB/s. I feel like even though I have... (1 Reply)
I have a file that is 20 - 80+ MB in size that is a certain type of log file.
It logs one of our processes and this process is multi-threaded. Therefore the log file is kind of a mess. Here's an example:

How do I create individual tars of a all the directories in a directory? I have a directory called 'patients', each patient has a directory in the patients directory. I want to create tars such that each patient has their own tar file.
Thanks! (5 Replies)
The below bash will untar each tar.bz2 folder in the directory, then remove the tar.bz2.
Each of the tar.bz2 folders ranges from 40-75GB and currently takes ~2 hours to extract. Is there a way to speed up the extraction process?
I am using a xeon processor with 12 cores. Thank you :).

shtool-tarball
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.
