These popular methods of backup are: left to right (incremental), mirror A->B or vice versa, synchronise AB, etc. Most of the open source backup software uses various synchronisation methods to take data backups. Many third party vendors provide cloud backup services. This is known as remote backup.Ĭloud backup: A cloud backup uploads the source disk data to cloud servers directly. Remote backup: Sometimes, IT administrators take backups of distant computers remotely without physically accessing them. Mostly, the storage disk is directly connected to the source computer. Local backup: Local backup refers to a backup when the destination disk is kept close to the source disk. Files need to be individually compressed if required. But unlike full backup, mirror backup doesn’t allow compression of all files together. Mirror backup: Mirror backup is quite similar to a full backup. If the source disk has a change of data or new data was added to it, then incremental backup automatically adds the newly created extra data only.ĭisk imaging: Disk imaging is the process of creating an archive of the source disk to a destination disk, which can be later used for making more copies of the hard drive.ĭisk cloning: Disk cloning creates a clone of the source disk into another hard drive. Incremental backup: Incremental backup acts as an add-on to the already existing backup. The ten open source backup tools included in this list are full-featured, offering an expansive list of capabilities for a variety of users.įull disk backup: Copying the complete source data files, including the associated settings and configurations of the whole computer system or hard drive, is called full disk backup.ĭifferential backup: Copying only those files that have changed since the last backup refers to the process of differential backup. With source code that anyone can inspect, modify or enhance, open source backup software is easily managed, and is designed to be publicly accessible and maintained by organisations with a specific mission in mind. Some of the software also offers the flexibility to back up data online. Apart from backup, you can also restore data through this software. In some cases, you can also back up registry data along with normal data. Most backup software can save the backup in local storage or in a portable storage device. These backups are strongly recommended for computer users, as data loss can be extremely frustrating. Open source backup software is designed to automate the process of backing up, making it easier for organisations and individuals to back up their files regularly. This article outlines the ten top open source solutions for backup, and explains why they are needed. There are also fun things to try, hardware, free programming books and tutorials, and much more.No business can do without deploying standard backup software in its IT systems, as these help to prevent the loss of data. There are hundreds of in-depth reviews, open source alternatives to proprietary software from large corporations like Google, Microsoft, Apple, Adobe, IBM, Cisco, Oracle, and Autodesk.
