Does VSS increase backup speed

[Puffy]

Hi,I was wondering beside using VSS to backup open files, can VSS help to speed up backup speed ?

In additional, will increasing the VSS size helps as well in terms of backup speed.

Thanks.

No is inverse the speed is decreased because VSS what is doing is saving every file that was in use and until is release the backup will end and during this time the checking process consumes resources making your backups go slow.

here is a very good explanation of how it works
