Commands using tar

create tar.bz2 package from files "-type f" modificated today "-mtime -1" in ~/project

Add z to the flags to enable compression.

Notes:

* Adjust the find command to your own filters.

* The -P flag forces to keep absolute paths in the tarball, so that you can be sure that the exact same file hierarchy will be created on the second machine.

These days, most software distributed in tar files will just contain a directory at the top level, but some tar files don't have this and can leave you with a mess of files in the current folder if you blindly execute

This command can help you clean up after such a mistake. However, note that this has the potential to do bad things if someone has been *really* nasty with filenames.

You can exclude more system folders or individual files which are not necessary for the backup and can be recreated after the restore procedure, like /lost+found, /mnt, /media, /tmp, /usr ...

Restoring the above backup procedure is as simple as becoming root and typing:

You can extract any file or directory out of the backup.tgz file for recovery, for instance, if you have a corrupt or mis-configured fstab file, you could simply issue the command:

Other options:

v add verbose option to see files processed

A far safer solution is to restore the desired files under a different directory, and then compare, move, or update the files to their original locations afterward.

This command tar?s up a directory and sends the output to gzip, showing a rate of 223MB/s.

This may require you installing the pv command.

For debian based users out there:

This is a little bash script that will take all files following the *gz pattern in the directory and apply the tar -zxvf command to them.

I use this all the time for taking manual backups of stuff i want to keep but not important enough to backup regularly.

tar options may change ;)

c to compress into a tar file, z for gzip (j for bzip) man tar

-print0 and -0t are usefull for names with spaces, \, etc.

uses tar to dump files from /orignl/path to /dst/dir. i find tar's out more readable than cp, and it doesn't mess with modified dates.

due to bug can not comment

A useful bash function:

gztardir()

{

if [ $# -ne 1 ] ; then

echo "incorrect arguments: should be gztardir "

else

tar zcvf "${1%/}-$(date +%Y%m%d-%H%M).tar.gz" "$1"

fi

}

Create a tgz archive of all the files containing local changes relative to a subversion repository.

Add the '-q' option to only include files under version control:

Useful if you are not able to commit yet but want to create a quick backup of your work. Of course if you find yourself needing this it's probably a sign you should be using a branch, patches or distributed version control (git, mercurial, etc..)

Creates a quick backup with tar to a remote host over ssh.

tar's directory and sends to netcat listening on port 10000

On the client end:

netcat [server ip] 10000 | tar xfvz -

This will send it over the network and extract it on the clients machine.

it compresses the files and folders to stdout, secure copies it to the server's stdin and runs tar there to extract the input and output to whatever destination using -C. if you emit "-C /destination", it will extract it to the home folder of the user, much like `scp file user@server:`.

the "v" in the tar command can be removed for no verbosity.
