Fbackup incremental backup11/10/2023 ![]() No data is transferred, except information that File 3 has been deleted. Again, only those changes are copied to the backup repository. On Tuesday, we add blocks 6 and 7 to File 2. It just copies the 1 changed block of File 1 and sends the information that this block must replace block 1. When using incremental technology, a backup application does not copy the three files or the four blocks of File 1. On Monday, we change block 1 to block 5 in File 1. The initial full backup is made on Sunday. In our example, there are 3 files in a VM, and each file consists of four data blocks numbered 1 through 4. Synthetic full: A backup is created using the last full backup and all subsequent increments (in the backup repository), without using the production resources.īelow is an example of how incremental backups work.Active full: A backup is created using the source machine.Thus, during recovery, the backup solution relies on the most recent full backup file and the increments made after it instead of “replaying” all increments starting from the initial backup.īackup software usually allow you to create a full backup manually or automatically using either the active full or the synthetic full backup method: With this incremental backup approach, it is recommended that full backups are created periodically to to benefit from the advantages of both methods, that is, shorter backup windows, storage savings and improved recovery speed. ![]() ![]() Initially, a full backup is created and then a chain of incremental backups follows. This way, only the necessary amount of data is transferred to ensure zero data loss. Incremental backup is a backup method whereby only the data that has been created or modified since the last backup run is copied to the repository.
