Differential Backup Mode

Differential backup mode works by storing on each execution only the detected differences between the current virtual machine state and a full, original backup made on the first run. In the example below, on Monday the first full is created. Then, on each following day only the differences from the original full backup are stored.



Once the maximum retention value has been reached, VSquare will consolidate the latest full to the nearest differential restore point and continue creating differential backups forever.



By storing only differences you can greatly reduce the amount of space required for a multiple days retention. Differential backup uses more space than Incremental backup but when restoring, only the original full backup and the current differential storage are required. As a result, Restore speed will increase and the corruption or destruction of any backup between the original full and the required differential day will not compromise any data.

Differential backup is available starting from Professional plans.

Differential backup is not available on Free VMware ESXi, regardless of VSquare licensing.
