As a Linux professional, having reliable backups is one of the most critical elements for protecting systems and data. In my many years administering Linux infrastructure, I‘ve depended on various backup tools to safeguard everything from small single board computers to enterprise grade servers.
In this comprehensive guide, I‘ll explore 11 of the best open source Linux backup tools capable of handling a wide range of use cases.
1. Rsync – Powerful Command Line Backup
Rsync is one of the most popular and flexible command line backup tools included in almost every Linux distribution. With rsync, you can perform fast incremental file transfers, synchronize data between locations, and schedule background copies.
While the syntax can be intimidating for beginners, rsync is a swiss army knife for scripting automated backups. For graphical usage, Grsync provides an accessible interface while retaining access to rsync‘s vast capabilities.
Pros: Lightweight, fast transfers, encryption, remote syncing, automation/scripting
Cons: Steep learning curve, CLI focused
2. Timeshift – Easy System Rollbacks
For Linux Mint users, Timeshift is an indispensable tool for system protection. It takes periodic snapshots of the file system and important configurations, allowing you to rollback entire systems in case of problems.
I rely on Timeshift before doing major upgrades, installations, or configuration changes where failure would be disastrous without quick rollback. The interface is straightforward with options to schedule recurring snapshots or initiate them manually.
Under the hood, Timeshift leverages rsync to minimize occupied disk space with hard links. Ext4 and Btrfs file systems are best to limit snapshot overhead.
Pros: Simple interface, mint integration, bootable snapshots
Cons: Mint focused, snapshot storage overhead
3. Bacula – Robust Client/Server Backup
For robust enterprise grade backup, Bacula offers extensive capabilities despite its open source status. As a long time SysAdmin, I‘ve deployed Bacula for small businesses up to large scale multi-petabyte backups.
A major advantage of Bacula is its modular client/server architecture, allowing single administration of backups across entire networks. Bacula integrates with everything from tapes to cloud object storage for ultimate hardware flexibility.
With meticulous logs and verification, Bacula gives me confidence in disaster recovery readiness. I‘ve restored whole systems from bare metal backups with it many times. The learning curve is steep, but worth it!
Pros: Tape support, bare metal restore, remote clients, extensive logs/verification
Cons: High complexity, database dependencies
4. Amanda – Mature Open Source Backup
Developed at the University of Maryland, Amanda is a venerable open source backup solution catering to power users. At a previous company, Amanda let us backup multiple foreign branch office servers over VPN into a centralized data center.
A major perk of Amanda is its native exploitation of Linux backup facilities like dump. Setup requires meticulous planning, but pays dividends allowing automation of everything from incremental single file backups to full bare metal images.
Support for plugins and integration with standard Unix utilities gives Amanda adaptability. There‘s a learning investment, but Amanda has the longevity and feature set for advanced workloads.
Pros: Bare metal restores, client/server architecture, cloud capabilities
Cons: Manual configuration, high learning curve
5. CloudBerry Backup – Backup to The Cloud
For secure cloud backup, CloudBerry Backup is my go-to solution for Linux. With compression and encryption options plus block level incrementals, CloudBerry makes efficient use of cloud storage costs.
I utilize CloudBerry to archive old system images offsite in Amazon S3 for disaster recovery with minimal overhead. The backup sets are bootable, keeping old kernel versions intact for maximum compatibility.
Whether using the command line interface or browser based UI, CloudBerry streamlines cloud integration. Managing multiple backup sets is easy with a centralized management console and monitored dashboard.
Pros: Block level incrementals, cloud support, encryption, bootable images
Cons: Cloud costs can add up
6. Clonezilla – Imaging & Cloning Backup
When I need exact machine duplication on Linux, Clonezilla is the go-to tool. Through disk imaging, Clonezilla flawlessly migrates systems to identical or dissimilar hardware.
I once migrated a dozen aging Ubuntu 16.04 servers onto new hardware quickly by network booting Clonezilla and imaging the disks over multicasting onto new NVMe machines. The servers were back online within hours with zero issues.
Multicasting allows scaling massive Clonezilla workloads – I‘ve done up to 100 simultanous server migrations! Beyond cloning, Clonezilla archives images to various destinations like SMB shares or S3 too.
Pros: Exact duplication, multicasting, dissimilar hardware migration
Cons: Destructive restores, not focused on file backup
7. Back In Time – Simple Snapshotting
For basic home backups, Back In Time offers an easy solution by snapshotting files into archive folders. The interface configures recursion rules to grab selected directories like /home. I schedule it nightly on my kids‘ Linux laptops.
Leveraging rsync and hardlinks, Back In Time minimizes occupied space for its archives. The backup location can even be remote over SSH. Compared to full images, snapshotting works better for user files.
For power users, more advanced configuration comes by directly editing rules and profiles. But for most purposes, the GUI has just the right options for simple snapshotting and restoration.
Pros: Simple snapshotting, space efficient archives, encryption
Cons: Less features than contemporaries
8. BackupNinja – Lightweight Incremental Backup
For flexible incremental backup on Linux servers, BackupNinja comes feature packed despite a tiny footprint. The backups chain together via rules and directives in the /etc config directory.
I utilized BackupNinja in my early days starting out as a junior Linux admin. It strikes a nice balance between ease of use and configurability for things like scheduling, retention policy, notifications/reporting, logging, and exclusions.
Compared to fuller featured solutions, BackupNinja excels at simple daily incremental server backups. It makes short work of /etc, user files, MySQL dumps, and similar filesystem subsections.
Pros: Rule based config, incremental backups, email notifications
Cons: No compression/deduplication
9. BackupPC – High Performance Data Deduplication
For backing up huge datasets from multiple similar Linux machines, BackupPC leverages aggressive data deduplication and compression to minimize backups down to just the differences.
I currently use BackupPC to consolidate backups for over 30 virtual machine hypervisors by storing just one full backup and sending incremental changes from there on rather than full weekly copies. This saves enormous amounts of capacity.
Despite deduplicating backups from many sources down to a centralized storage server, BackupPC achieves amazing throughput thanks to optimization for LAN environments and idle priority scheduling.
Pros: Block based deduplication, LAN optimized, web interface
Cons: Agentless limiting OS support
10. Fwbackups – User Friendly Backup Solution
For easy ad-hoc personal backups, fwbackups provides a simple file copy graphical interface to safeguard data. Behind its straightforward design, efficiency features like compression, Bloxxing, permissions preservation, and bz2 creation aid rookies and veterans alike.
I keep fwbackups portable on my administration jump server‘s flash drive for occasions I need to urgently grab backups from machines without pre-installed enterprise backup agents. Despite being single user focused, ssh remote access gives fwbackups deployment versatility covering most common scenarios.
Pros: Approachable UI, compression/deduplication, archives permissions
Cons: Single user, no scheduling
11. Burp – Advanced Backup Tool
For backing up Linux desktops and servers, Burp‘s unique capabilities speed up workflow. Its segmented file backup support avoids uploading gigantic files repeatedly thanks to checksum blocking and staging.
Once, stuck with a slow uplink and very large media assets, Burp sliced files for continued backup retries rather than starting the entire upload again each failure. Burp tackles such cases with aplomb where other tools stumble.
Coupling redundancy support with powerful restoration, scheduling, throttling, reporting, multi-location backups, client/server architecture, and software package integration like VSS on Windows, Burp is a swiss army knife specialized for just backup!
Pros: Block/checksum resuming, client/server architecture, bandwidth throttling
Cons: Configuration complexity
