README.md

backup-server

Backup and download scripts to compress with:

  • Gzip (DEFLATE)
  • Bzip2 (BWT)
  • XZ (LZMA2)
  • 7Z (LZMA)
    • Not Recommended (not save file permissions and structure is messy)

The backup script (backup-server) backup the following server configuration:

  • Web Sites (/var/www)
  • SQL Databases (MySQL or MariaDB)
  • HTTP Server Configuration (Nginx)
  • Let's Encrypt Certificates
  • Home Directory (/home)
  • GOGS Git Repository
  • Mail Mailboxes (/var/mail)
  • Postfix MTA Configuration (SMTP mail server)
  • Dovecot MDA Configuration (POP3/IMAP server)
  • OpenDKIM Configuration (Anti email spoofing)
  • postfix-policyd-spf-python Configuration (Anti email spoofing)
  • OpenDMARC Configuration (Anti email spoofing)
  • Amavis Configuration (Antivirus)
  • SPAM Assasin (AntiSPAM)

Also it's:

  • Autoremove old backups
  • Set backup dir
  • Encrypt backup (gpg2)
  • Create SHA512 Hash (to check integrity)

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 in scripts folder.

Download scripts

The download script (download-backup-http) download all the compressed files in a remote machine, via http/https (with Auth Basic Aunthentication).

The download script (download-backup-sftp) download all the compressed files in a remote machine, via sftp (SSH File Transfer Protocol).

Autodownload

To autodownload the backups from another machine there are multiple solutions.

  • Create autostart desktop file: to download backup when you login (examples).
  • Create a cron.d job: to download backups periodically.
