Backup Linux System
bls is tool for backing up of Linux system and files. It is made with following limitations:
- it only runs on UEFI systems
- there can be multiple EFI system partitions but they MUST have same content.
- it only backs up ext filesystems (btrfs, zfs and ntfs are not supported)
- backuped files are stored in single gziped tar ball
- there are no incremental backups
- tar file will/must be stored on samba share
- it is intended for Debian based system (this is consequence of the fact, that on installation of the scrip to the system, missing packages are also installed. That can change in future.)
Multiple packages/utilities have to be present on the system, for script to run. On installation of the script, presence of this packages is checked and if missing, they are installed.
Caveat is, that this works only on Debian based systems (Ubuntu and likes), since apt is used as package manager.
Clone repository to your system, cd to bls directory and run:
sudo make install
This will install bls script into /usr/local/bin directory. It will also
install autocompletion configuration files for bash and zsh (if given shells are
installed on system). If given shell is installed afterwards, repeat installation
process to install missing autocompletion files.
You can remove bls from system by running
sudo make uninstall
This will not remove configuration file /etc/bls.conf if one has been
created.
By runnins script bls without any parameter, basic help will be displayed
