Subject: Linux commands I used to backup my Contabo VPS Ubuntu Linux iRedMail Mail Server
Good day from Singapore, These are the Linux commands I used to backup my Contabo Virtual Private Server (VPS) Ubuntu Linux iRedMail Mail Server. Yes, I have a virtual private server in the Federal Republic of Germany. Detailed instructions follow. Change directory into the root directory of your Linux server. # cd / GNU tar is a backup utility for Linux systems. # nohup tar -cvpjf backup.tar.bz2 \ --exclude=/backup.tar.bz2 \ --exclude=/nohup.out \ --exclude=/swapfile \ --exclude=/proc \ --exclude=/tmp \ --exclude=/dev \ --exclude=/sys \ --exclude=/run / & Monitor the progress of the backup job. # tail -f nohup.out Check if the backup job has finished/completed. # ps -ef | grep tar Check the filesize of your final backup file. # du -h backup.tar.bz2 2.8G backup.tar.bz2 On Windows 10, the filesize of my backup file is 2.75 GB. Rename the backup file so that it is more descriptive. # mv backup.tar.bz2 contabo-ubuntu-iredmail-24sep2021.tar.bz2 Transfer the backup file *.tar.bz2 to your off-site backup destination. I chose bz2 over gzip because it has a higher compression, resulting in a smaller filesize. XZ has an even higher compression but the compression process is slower than bz2. Then, # rm contabo-ubuntu-iredmail-24sep2021.tar.bz2 # rm nohup.out Reference Guide: BackupYourSystem/TAR Link: https://help.ubuntu.com/community/BackupYourSystem/TAR Reference Guide: How to Run Linux Commands in Background Link: https://linuxize.com/post/how-to-run-linux-commands-in-background/ Information =========== My Ubuntu Linux server is Ubuntu 18.04.5 LTS (GNU/Linux 4.15.0-142-generic x86_64). 64-bit platform.
