I want to take tar from a logged in shell and take that tar file to a remote host and then extract the tar file over there. I've got below command but the tar itself is not creating.
time=`date` timestamp=`date +%F_%H%M` backpfilename=db${timestamp}.tar.gz cd /home/aryan/ && tar -cvzf $backupfilename | ssh root@remoteserver 'cd /home/aryantest/ && tar -xvzf $backpfilename' You can extract the tar file directly on the other side without writing it to disk:
tar czv <files>| ssh root@remoteserver 'cat | tar xz -C /remotedir'
You can use this even with netcat to copy files around.
If you want a progress bar you can use pv for this. It will print the speed to stdout so you can check how fast it is copying:
tar czv <files> | pv | ssh root@remoteserver 'cat | tar xz -C /remotedir'
If you already have that tar file, you can use pv to pipe it through ssh:
pv backupfile.tgz| ssh root@remoteserver 'cat | tar xz -C /remotedir'
Try this :
cd /home/aryan tar cfvz /dev/stdout . | ssh root@remoteserver 'cat > file.tar.gz && tar zxvf file.tar.gz' You just need to adapt it a bit
/dev/stdout can be replaced by -.
The basic way to create compressed files with tar is : tar opts file.ext dir/. Here we explicitly replace the destination filename with STDOUT to be able to stream it via ssh.
