NAKIVO Video: Skip Swap File Video
Since the swap file can automatically grow up to 3X the size of RAM, this means that gigabytes of unnecessary data are processed, transferred, and stored in the backup repository each time you back up a VM. NAKIVO Backup & Replication v7 automatically skips the swap file in VMware and Hyper-V VMs, which speeds up data transfer and saves storage space in a backup repository.
