  • This command will backup the entire / directory, excluding /dev, /proc, /sys, /tmp, /run, /mnt, /media, /lost+found directories. Let us break down the above command and see what each argument does. rsync: A fast, versatile, local and remote file-copying utility -aAXv: The files are transferred in ?archive? mode, which ensures that symbolic links, devices, permissions, ownerships, modification times, ACLs, and extended attributes are preserved. -/: Source directory -exclude: Excludes the given directories from backup. -/mnt: It is the backup destination folder. Please be mindful that you must exclude the destination directory, if it exists in the local system. It will avoid the an infinite loop. To restore the backup, just reverse the source and destination paths in the above command.

    rsync -aAXv / --exclude={"/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/home/*","/lost+found/*"} <backup path> > <path_of log file>

  • 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: tar zxpf backup.tgz -C / 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: tar zxpf backup.tgz /ect/fstab -C / 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.

    tar zcpf backup.tgz --exclude=/proc --exclude=backup.tgz /

  • sed already has an option for editing files in place and making backup copies of the old file. -i will edit a file in place and if you give it an argument, it will make a backup file using that string as an extension.

    sed -i.bak 's/old/new/g' file
