Top Bacula Alternatives for Linux/Windows Backup: Simplified Open-Source Solutions


2 views

Many sysadmins share your frustration with Bacula's steep learning curve. The configuration files (/etc/bacula/bacula-dir.conf) require manual editing, job definitions involve multiple components, and troubleshooting often means digging through verbose logs. For example, a simple backup job requires:

Job {
  Name = "ExampleBackup"
  JobDefs = "DefaultJob"
  Client = "client-fd"
  FileSet = "FullSet"
  Schedule = "WeeklyCycle"
}

Here are three battle-tested alternatives that maintain enterprise features while simplifying operations:

1. Bareos (Bacula Fork)

The spiritual successor to Bacula with improved web UI and simplified configuration. Installation on Ubuntu:

sudo apt install bareos-director bareos-webui
sudo systemctl start bareos-dir bareos-sd bareos-fd

Key differentiators:

  • Web-based configuration (port 9100)
  • Native cloud storage support
  • Built-in reporting dashboard

2. Restic

For those preferring simplicity and cloud-native workflows. Sample backup script:

#!/bin/bash
restic -r /backup/repo \
  --exclude-file=/etc/restic/excludes \
  backup /home /etc /var

Advantages:

  • Single binary deployment
  • Deduplication by default
  • Works with S3, Backblaze, MinIO

3. BorgBackup

The compression champion with client-side encryption. Sample cron job:

0 3 * * * borg create /backup::'{hostname}-{now}' /etc /home \
  --exclude '/home/*/cache'

When evaluating alternatives, test these critical scenarios:

  1. Cross-platform restore (Windows → Linux)
  2. Incremental backup performance
  3. Encryption key management

Example restore test with Borg:

borg list /backup
borg extract /backup::server-2024-03-15 etc/ssh/sshd_config

While Bacula remains a powerful enterprise-grade backup solution, many sysadmins find its architecture unnecessarily complex for routine operations. The separate director, storage daemon, and file daemon components create management overhead, especially when dealing with mixed Linux/Windows environments.

We considered these key factors when selecting alternatives:

  • Native support for both ext4/XTFS and NTFS/ReFS
  • Efficient delta/differential backups
  • Modern API/CLI interfaces
  • Active community support

1. Bareos (Bacula Fork)

The most natural transition path, maintaining Bacula's core functionality while simplifying deployment:

# Ubuntu/Debian install:
sudo apt install bareos-director bareos-storage bareos-client
# Windows client available via .msi installer

Key advantage: Uses same .conf syntax while adding web UI and better plugins

2. Restic

Lightweight solution with brilliant deduplication:

# Initialize repo (works cross-platform):
restic -r /backup/repo init
# Backup Windows machine from Linux server:
restic -r sftp:user@windows-host:/backup backup C:\\

3. Duplicati

Best for cloud integration with local cache:

# Sample CLI backup (also has GUI):
mono Duplicati.CommandLine.exe backup \
  sftp://backup-server/path \
  --dbpath=/local/cache.db \
  --encryption-module=aes \
  --passphrase-file=/etc/duplicati.key

When transitioning from Bacula:

  • Maintain parallel runs during transition period
  • Convert Bacula catalog data using bscan utility
  • Test restore procedures thoroughly before decommissioning
