 # backuper
  
-## Usage
-
-### Incremental backup
-
-```sh
-backuper i <config file path>
-```
-
-### Full backup
-
-```sh
-backuper f <config file path>
-```
-
-### Search files in backup
-
-```sh
-backuper s <config file path> <mask>
-```
-
-### Recover files from backup
-
-```sh
-backuper r <config file path> <mask> <files datetime> <path to recover>
-```
-
-Examples:
-
-```sh
-# Recover Go files relevant as of 01.01.2023 to /home/user/go directory
-backuper r config.conf "*.go" "01.01.2023" "/home/user/go"
-```
-
-### Test backup for errors
-
-```sh
-backuper t <config file path>
-```
-
-## Basic config example
-
-Backup config files from `/etc` and sqlite files from `/var`:
-
-```toml
-FileName = "backup"
-
-[[Patterns]]
-Path = "/etc"
-FileNamePatternList = ["*.conf", "*.toml", "*.ini", "*.yaml"]
-Recursive = true
-
-[[Patterns]]
-Path = "/var"
-FileNamePatternList = ["*.sqlite"]
-Recursive = true
-```
