What is Initial Seeding?
Initial Seeding is an extra service that lets you save an initial full backup locally and then send it to Acronis on a hard disk drive.
Acronis uploads the backup to the online storage. After that, you can add incremental backups to this full backup, either manually or on a schedule.
The hard disk drive is sent back to you but it is not possible to recover from it. However, recovery from a locally attached device is possible with the Large scale recovery option.
