If you search for a feature rich backup script working on linux, give glsysbackup a try. It is still under active developement and is available on github:

glsysbackup

(generic linux system backup) is an advanced backup tool written in bash.

Features:

Lock functionality. Only one instance is possible to run. (Lock file and check with pgrep)
Verbose logging to stdout and/or system logfile and/or system journal and/or individual logfile.
Excluding of files
Backupfile rotation (daily || weekly || monthly)
Creates a file with installed packages (rpm || dpkg || pacman || equery || pkgutil)
Encryption with openssl
CLI options and arguments
Renicing
Re-ioniceing
Execution of pre-backup-script
Execution of post-backup-script

Description:

Check if the required binaries exists
Set configuration of logHandler
Check if glsysbackup should be exectuted with root privileges
Get and log the user, who starts glsysbackup
Check if bash version meets requirements
Check if an instance is already running via lockfile and pgrep
Re-nice glsysbackup if required
Re-ionice glsysbackup if required
Create backup directory structure
Execute the pre-backup-script, if it is defined and executeable
Create file with installed packages
Build excluding options from config array
Build the backup options from config
Make the tar backup
Enrypt the backup with openssl if required
Execute the post-backup-script, if it is defined and executeable
Rotation of backup files if backup/encryption was successful

It requires the following binaries:

bash (Version >= 3)
pgrep to check if an instance of glsysbackup is already running
whoami to check the user who executes glsysbackup
date for logging purposes (Only required if bash version < 4.2. Else printf bash builtin will be used.)
tar to create the backup
rm to delete files
cp to copy files
mkdir to create directories
kill to send kill signal to glsysbackup

Optionally used binaries:

logger to log to the system log
systemd-cat to log to the system journal
rpm || dpkg || pacman || equery || pkgutil to create a file with installed packages
openssl to encrypt the backup file
renice to renice glsysbackup and all child processes
ionice to re-ionice glsysbackup and all child processes

Installation:

Download the latest tarball and extract it:


cd /tmp
wget "https://api.github.com/repos/ccztux/glsysbackup/tarball" -O glsysbackup.latest.tar.gz
tar -xvzf glsysbackup.latest.tar.gz
cd ccztux-glsysbackup-*

Copy the files:


cp -av ./usr/local/glsysbackup/ /usr/local/
cp -av ./etc/logrotate.d/glsysbackup /etc/logrotate.d/

Change the file ownership:


chown -R root:root /usr/local/glsysbackup/
chown root:root /etc/logrotate.d/glsysbackup
chmod 644 /etc/logrotate.d/glsysbackup

Edit the config:


vim /usr/local/glsysbackup/etc/glsysbackup.conf

Start glsysbackup:


/usr/local/glsysbackup/bin/glsysbackup -c /usr/local/glsysbackup/etc/glsysbackup.conf
