As one of the most prominent and open-source software collaborations, Linux is the leading operating system on 3 types of servers including Linux File Server, Linux Web Server, and Linux Database Server with extensive distributions like Debian, openSUSE, Fedora Linux, Ubuntu, and hundreds of others.

Known for their scalability, high-end security, and flexibility, Linux servers are widely used among over 1 million organizations, which entail complete and reliable data protection against threats such as hardware failure, system downtime, or cyberattacks.

Backups are proven practices to avoid data loss in disasters. It is not only important but also necessary to know certain effective backup and recovery options for Linux servers. You can backup Linux files/folders and servers to multiple destinations in various ways. In this article, I'll give you 7 easy ways to protect Linux server data comprehensively.

Way 1: Using Rsync and Cronopete

Rsync is a Linux-based utility often used to transfer and synchronize files and directories locally, to and from another host using any remote shell or to and from a remote rsync daemon.

Parameters:

-verbose, -v  increase verbosity.
-stderr=e|a|c change stderr output mode (default: errors).
-quiet, -q suppress non-error messages.
-backup, -bcreate backups (see --suffix & --backup-dir).
-backup-dir=DIRcreate backups into a hierarchy based on DIR.
-suffix=SUFFIX backup suffix (default ~ w/o --backup-dir).
-update, -u exclude files that are newer on the receiver.
-checksum, -cskip based on checksum.
-fake-superstore/restore privileged attrs using xattrs.
-exclude=PATTERN rule out files matching PATTERN.
-exclude-from=FILE  read exclude patterns from FILE.
-include=PATTERNinclude files matching PATTERN.
-include-from=FILE read include patterns from FILE.

For the whole option summary, visit Rsync website.

Linux Server Backup

1.     Insert the backup medium and locate the drive letter with \'fdisk -l\' command.

2.     Open your terminal and run the following commands:

$ sudo rsync -aAXv / --exclude={"/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} /target_folder

This backs up the entire root directory except /dev, /proc, /sys, /tmp, /run, /mnt, /media, /lost+found directories and saves them in the target folder.

3.     Backup a home directory with large MS Word files and mail folders:

rsync -aiz . bkhost:backup/user_name/

Linux Server Recovery

Cronopete is a Linux clone of Time Machine and a backup tool for Mac. You can copy and restore all the user files on a separate hard disk, but it is not for the backup of the whole operating system.

1.     Install Cronopete and type the following command from the terminal:

$ cronopete

2.     Click Configure now on the welcome page.

3.     Plug in the external HDD or USB and click Change disk.

4.     Choose your USB disk and click Select. Repeat the step for other backup disks.

5.     Click Format disk to format the disks for backups.

6.     The tool immediately starts to back up the entire $HOME directory by default. You can define the backup objects from the Options section and specify the time interval between backups.

7.     To restore the data, right-click the Cronopete icon on the menu and select Restore files. Next, choose the source files or folders from the backup USB and click Restore files on the top left.

Way 2: Using Bera

Bera is a backup system to easily backup all the important files, and folders, serves configuration, and restore them in the same server or move to another one. This tool can perform full backup and recovery, and migrate a complex server in 10m. It is also able to exclude domains, files, and folders, and uses SSH to secure transmission.

Parameters:

backupOriginrefers to local if the backup is on the server or SSH if it is from other locations.
backupLocalDirlocal directory where the backup is located.
backupRemoteUser connect to the backup server via SSH.
Backupremoteserver remote SSH backup server.
backupRemotePortSSH server port.
backupRemoteDirremote backup directory.

Linux Server Backup

Preparation:

  • Linux server

  • Rsync

  • SSH

  • Root access to both the source and target systems

1.     Install the SO, config network, install packages, etc., to configure the server.

2.     Download service configurations, files, folders, and others using Bera.

3.     Upload the following files to the server and set permissions:

chmod +x bera-backup.sh

chmod +x bera-restore.sh

The config file of each script needs like _bera_restore_config_example and _bera_backup_config_example

4.     Backup a Linux server in the designated folder:

./bera-backup.sh PATH_TO_CONFIG_FILE

Linux Server Recovery

Download the backup from the server and restore:

./bera-restore.sh PATH_TO_CONFIG_FILE

Way 3: Using Tar

Tar, short for tape archive, is to compress and archive multiple files and directories for easy storage distribution, known as a tarball. It creates backups using tar, gzip, and bzip.

Parameters:

-c create a new archive.
-v offer verbose output.
-f define the archive file to be used.
-t  make a list of the files in an archive.
-x extract the backup.
-z  zip.

Linux Server Backup

1.     Create a tar backup.

# tar -cvf backup­_name.tar /home/user

2.     Create a tar.gz backup.

# tar -cvfz backup_name.tar.gz /home/user

3.     Exclude the files.

# tar --exclude file.txt --exclude file.sh -cvfz backup_name.tar.gz

4.     Extract content from a backup.

# tar -xvfz backup_name.tar.gz /backup/directory/file.txt

5.     Archive all files in the server into a gzip format, exclude the backup created earlier, and create a new directory for backup. Make sure that the server is not in maintenance mode.

sudo tar –cvpzf backup_name.tar.gz –exclude=/home/server/backup.tar.gz –one-file-system

Linux Server Recovery

Restore the tar.gz backup.

# tar -xvpf /media/your_harddisk/backup.tar.gz

Way 4: Using Cpio

Cpio, copy in/out, is a file archiver utility to create and extract archives or copy files to another place.

Parameters:

-O read the standard input.
-i extract files from the standard input.
-c read or write the header information in ASCII character.
-d create directories if needed.
-u copy unconditionally so the new file won’t overwrite the older file.

Linux Server Backup

1.     Backup the files.

#ls  file *  /cpio  -acvf  >/root/backup.cpio

2.     View the backup content.

#cpio -it </root/backup.cpio

#cpio -it -I /root/backup .cpio

Linux Server Recovery

Restore the backup files.

#cpio  -icuvd  </root/backup.cpio

Way 5: Using DD Command

DD (Disk to Disk) creates the backup of one partition to another.

Linux Server Backup

1.     Create the backup.

#dd   if=source_partition  of=destination_partition

2.     Create a duplicate partition with the existing partition without creating any backup file.

dd if=existing­_source­­_partition of=destination­_partition

Linux Server Recovery

Restore the backup partition to another empty partition.

#dd   if=destination_partition of=another­_empty_partition

Way 6: Using SCP and Timeshift

SCP (Secure Copy) copies data from one Unix/Linux system to another in the same machine, from the local machine to the remote machine and vice versa, or between different remote servers.

Parameters:

-r recursively.
-q no progress indicator is shown.
-vverbose mode.
-pcopy files with the specified port number.

Linux Server Backup

Preparation:

  • Have permission to copy files on the target system.

  • Have either an account on the target machine or an authorized public key on it.

  • Have read permission on the source machine and write permission on the target.

1.     Copy the file from the local to a remote server.

#scp filename root@serverxxx.example.com:/root

2.     Copy files from the remote to the local server.

#scp  root@serverxxx.example.com:/root/backup*

3.     Replicate a directory.

#scp –r directory root@serverxxx.example.com: /root

4.     Use blowfish or arcfour encryption to improve performance.

#scp   -c  blowfish filename  root@serverxxx.example.com.com:  

5.     Specify the port number.

#scp -p  xxxx   backup_file  root@serverxxx.example.com:/tmp

Linux Server Recovery

Timeshift is a system restore tool pre-installed on some Linux distros and allows for point-in-time recovery.

1.     Install Timeshift in the terminal.

On Ubuntu and derivatives:

sudo add-apt-repository -y ppa:teejee2008/timeshift
