Backup is to copy and save important data or files to another place to achieve data synchronization between different hosts. And backups on personal computers or servers are important to prevent data loss. System administrators need to process a large amount of enterprise level data every day, even the data on personal computers, so they need to have a deep understanding of different backup tools. This article will introduce 5 backup tools for you to use on Linux servers or systems.

“My customer problem is deployment in physic server is difficult but technical suppport from Vinchin is helpfull.”

“The backup log ist not showing the task duration for a single VM. Sometimes Vinchin is not able to delete a backup snapshot (not furter investigeted yet — maybe my fault).”

“And another one we choose it because Vinchin charges reasonably.”

“Not much information during error logs to sometimes trouble shoot.”

AMANDA, the Advanced Maryland Automatic Network Disk Archiver, is a backup solution that allows the IT administrator to set up a single master backup server to back up multiple hosts over network to tape drives/changers or disks or optical media. Amanda uses native utilities and formats (e.g. dump and/or GNU tar) and can back up a large number of servers and workstations running multiple versions of Linux or Unix.


“Highly customisable, Doesn’t miss a backup if you forget to insert the target media. Can incorporated scripts. Workes better on Linux than windows.”


“Interface can be more polished.

Bad documentation.

Better Support”

Bacula is a set of Open Source, computer programs that permit you (or the system administrator) to manage backup, recovery, and verification of computer data across a network of computers of different kinds. Bacula free data backup software is relatively easy to use and very efficient, while offering many advanced storage management features that make it easy to find and recover lost or damaged files. According to Source Forge statistics (rank and downloads), Bacula is by far the most popular open source backup software tool for full system backup. It has 2,5 million downloads and thousands of contributors worldwide.


“I like it because it’s very extensible and can be used for customizing a mid-level enterprise. The File daemon once setup just runs smoothly without hassles.Everything we need is available on web platform on Bweb management console. There’s also option for Baculum support. I personally like because it’s feature includes Bare-metal backup VM Backup DB backup Cloud Backup Tape Backup Replication using Wan and Restoration.”


“The Enterprise edition is quite advantageous than the Community edition. Even though the trial version gives you all access to try Enterprise Edition version 8 features, VSS plugin, BWeb Management Suite etc. It’ll make you want to buy for service unlike Bare-os which started initially as a fork of Bacula is being considered as a better alternative to Enterprise edition”

Restic is a modern backup program that can back up your files:

from Linux, BSD, Mac and Windows

to many different storage types, including self-hosted and online services

easily, being a single executable that you can run without a server or complex setup

effectively, only transferring the parts that actually changed in the files you back up

securely, by careful use of cryptography in every part of the process

verifiably, enabling you to make sure that your files can be restored when needed

freely — restic is entirely free to use and completely open source


“Download a single executable that just works; which is available for multiple operating systems. Which does elegant stream deduplication (inserts in files are much better handled compared to regular block deduplication), and which is one of the fastest comparable. Which happens to be foss but not fuzz. Offers just a CLI. And even allows data from piped commands to be back-upped (think pg_dump) and saves almost only the differences. Using some smart setups you can even deduplicate across machines… What isn’t there to love?”


“The problem over the tool, why I set just 4 stars, that entry point very hard.

But with something like the code below, you can minimize headache.”
