 # backup-server
 
-Backup and download scripts to compress with 7z data for a debian server and download it to another machine.
+Backup and download scripts to compress with:
+* Gzip (DEFLATE)
+* Bzip2 (BWT)
+* XZ (LZMA2)
+* 7Z (LZMA)
 
 The backup script (**backup-server**) compress with 7z server info like:
-* Nginx configuration (sites-available)
-* MySQL Databases
-* Emails
-* Letsencrypt certificates
-* /home directories
+* Web Sites (/var/www)
+* SQL Databases (MySQL or MariaDB)
+* HTTP Server Configuration (/etc/nginx)
+* Let's Encrypt Certificates (/etc/letsencrypt)
+* Mail Mailboxes (/var/mail)
+* Home Directory (/home)
+* GOGS Git Repository (/opt/gogs)
 
 Also it's:
 * Autoremove old backups
-* Put it in a http/https server with Auth Basic Authentication.
+* Set backup dir
+* Encrypt backup (gpg2)
 
+## Instalation
+`# cp backup-server /usr/local/bin/backup-server`

+  * Make a backup in `/var/backup` compressed with Gzip and no encrypted (`/var/backup/backup-castanedo.es-2018-03-19-qwerty.tar.gz`)
+
+## Automatic Backups (Cron.d)
+It's possible to make backups automatic creating a cron.d task (`/etc/cron.d/backup-server`).
+
+There are an [example](https://code.castanedo.es/guzman/backup-server/src/master/scripts/cron.d/backup-server) in `scripts` folder.
+
+## Download scripts
 The download script (**download-backup-http**) download all the compressed files in a remote machine, via http/https Auth Basic Aunthentication.
 
 The download script (**download-backup-sftp**) download all the compressed files in a remote machine, via sftp (SSH File Transfer Protocol).
