$ tar cvzf - mydir/ | ssh "cat > /backups/myfile.tgz" $ tar cvjf - * | ssh "(cd /dest/ tar xjf -)" | pv | ssh "cat > /backups/box42/backup-dd-mm-yyyy.tgz" The pv command allows you to see the progress of data through a pipeline.
SSH COPY TO NAS APK
Hence, use the apk command on Alpine Linux, dnf command/ yum command on RHEL & co, apt command/ apt-get command on Debian, Ubuntu & co, zypper command on SUSE/OpenSUSE, pacman command on Arch Linux to install the pv.
SSH COPY TO NAS HOW TO
How to tar over SSH with progress barīy default, pv command may not be installed on your system. If you wish to use above command in cron jobs or scripts then consider SSH keys to get rid of the passwords. In this example, restore tar backup over ssh session from the remote machine to local dir: $ cat | ssh "cd /path/to/dest/ tar zxvf -" # tar cvzf - /wwwdata | ssh $(mt -f /dev/nst0 rewind cat > /dev/nst0)$ How to extract tar over ssh One can can use mt command to rewind tape and then dump it using cat command: # tar cvzf - /wwwdata | ssh "cat > /dev/nst0" # tar cvzf - /It is also possible to dump backup to remote tape device: You can also use dd command for clarity purpose: You can read more about tape drives naming convention used under Linux here. The default first SCSI tape drive under Linux is /dev/st0. $ ssh 'tar czf - /home/vivek' | tar xvzf -C /home/vivek Use tar command through network over SSH session for tape device Open the terminal on x230 laptop and run the ssh command along with tar command: The problem with scp and other command copying the directory structure is that Symbolic links, special devices, sockets, named pipes, and other stuff not copied. # ssh 'dd if=prod-disk-hostname-sdvf-dd-mm-yyyy.img' | dd of=/dev/sdvf Moving data to a new Linux system For instance, we can restore a local hard disk drive from the image stored on the remote AWS EC2 cloud backup server as follows: To restore a local drive from the image on the server, reverse the command. # dd if=/dev/sdvf | ssh 'dd of=prod-disk-hostname-sdvf-dd-mm-yyyy.img' Let us copy the entire hard disk drive named /dev/sdvf from local machine to the remote AWS EC2 cloud backup server: $ ssh 'tar zcf - /some/dir' | tar zxf - Linux system hard drive backup/mirror using tar and ssh # tar zcvf - /Use of tar command over ssh sessionsĬopying from the remote machine () to local system is as follows: To avoid this problem pass the -t option to the ssh command: Sudo: sorry, you must have a tty to run sudo Please note that you may get an error that read as follows with ssh command when using with sudo or any other command that needs a pseudo-terminal allocation:
