Attention: without parameter the program will do nothing

Running

To run the backup program you must start it with one of these parameters:

	-a | --all                    backup all container
	-cj | --cron                  backup script im cron modus, look in the docu for more information
	-c= | --container=            backup container
	-d= | --dir=                  path to the backup dir
	-doi | --delete-old-images    delete old images
	-doa | --delete-old-archives  delete old archives
	-s= | --sshport=              SSH Port
	-rs= | --rsyncpath=           Path for rsync target
	-h | --help                   show this help message
	-p= | --pass=                 password for gpg encryption
	-v | --version                print version & third party version

The easiest would be to do:

/usr/bin/bash lxdBackup.sh --all

Cron

To run the software in the cron modus start it with this parameter:

/usr/bin/bash lxdBackup.sh --cron

It is important that on of these two paramter is set:

export ALL_CONTAINER=y

or

export LXCCONTAINER=name-of-the-container

optional you can change the backup dir

export BACKUPDIR=/backup/

For GPG support look at the GPG section.

To get a log when you run the program in the cron mode just do something like this in your crontab:

#that will run every 4 hours
0 */4 * * * /usr/bin/bash /path/to/lxdBackup/lxdbackup.sh --cron > /path/to/log

GPG

To use the GPG encryption you must set the a GPG passphrase as a enviroment variable or at the begining of the script call:

/usr/bin/bash lxdBackup.sh --pass=myStrongPassword --all

Attention: It is important that the --pass= is the first parameter when you call the script!

The enviroment variable looks like this:

export GPGPASS=myStrongPassword

/usr/bin/bash lxdBackup.sh --all
