Hi,

I am experimenting with Acronis VMprotct, with the Incremental backup, it is saying bytes transmitted 70Gb however the destination hasn't increased by 70gb, only a couple Gb. Also it will say transfer rate of 3.5MB/sec, however the connection speed is only 8mbps. Is there something I am missing? Just trying to understand what it's actually doing and how it works.

Thanks

Mark

DeDupe/Compression/Only backs up changed content using Change Block Tracking (ie only blocks which have changed since last backup!) - makes a very efficient, quick backup.

Acronis VMprotect backup images are compressed that is why at destination you're not seeing 70GB disk usage.

Transfer rate shows the read data not the compressed data sent.

For example:  You have 10 MB data to backup. Software will show 10 MB data transfer rate but internally it will be compressed (assumption compressed to 1 MB). So it will write 1 MB at destination but 1 MB actually is 10 MB data (without compression) . So transfer rate is always the actual data size (without compression).
