backup-tool — this is a script for creating backups including incremental backups. The script is written in bash and using rsync for data processing , which provides high reliability, flexibility and scope.
As often happens, the script started his life as a small 2-line script for linux. In the future, so as not to duplicate each time the script for different installations (desktop computer, server, laptop, home windown pc, etc.) were introduced configuration. Now I can connect my new external hard drive, run the script, a few minutes of processing - the backup is created, with keeping of modified, deleted data.
