Incremental file backup

"Xiao Wang, do we need to back up our data?" "Andy, let's use a data backup software." "Lao Li, what is the best way to back up the data?" More and more companies (bosses) are beginning to value the data they have worked so hard to accumulate. However, with limited budget and manpower, how to build an efficient backup system is a headache for many IT personnel.

From the perspective of data backup methods, it can be roughly divided into full backup, incremental backup and differential backup. With the development of cloud computing, incremental backup has gradually become the backup method of choice for many small and medium-sized enterprises.

Incremental backup means that after a full backup or the last incremental backup, each subsequent backup only needs to back up the increased or modified parts compared with the previous one. This means that the object of the first incremental backup is the added and modified files generated after the full backup; the object of the second incremental backup is the added and modified files generated after the first incremental backup. files, and so on.

Incremental backup does not have duplicate backup data, so the amount of data backed up is not large, the time required for backup is short, and the required data storage space is small. Coupled with the price advantage of cloud storage, the overall cost investment will be further reduced. Moreover, cloud data backup can also eliminate the difficulty of recovery caused by damage to backup hardware.

Common incremental backup software (limited space, only three are introduced)

Multiple backups

Strictly speaking, multi-backup should be defined as a SaaS application. By connecting to public clouds, data can be backed up to public cloud platforms such as Alibaba Cloud and AWS. Although Multi-Backup also provides a client, it is basically managed through the web. Generally speaking, the operation and configuration are relatively simple. In addition to meeting the daily backup and storage needs of start-ups and personal websites, Multi-Backup also provides services for large companies. Personalization for the specific needs of medium-sized enterprises.

DeltaCopy

DeltaCopy is an open source fast incremental backup program. Let's say you need to back up 500mb files every night. A normal copying software will copy the entire file even if you only modified a few bytes of data. From another perspective, DeltaCopy will only copy the modified parts of the file. This method only transfers a small part of the 500mb file, saving time and network bandwidth.

FileGee

"FileGee Personal File Synchronization and Backup System" is an excellent file synchronization and backup software. It integrates file backup, synchronization, encryption, and recovery. It assists individual users to realize the synchronization between hard disks, mobile storage devices, and network disks. Backup and synchronization.
