fast question about tag "read"

[menced]

In the mail sent after a backup, the "Read" field in an incremental backup, mean the data read DIFFERENT from the first total backup?

I mean

Code: Select all

FULL BACKUP:

Name 	Status 	Start time 	End time 	Size   	Read 	Transferred 	Duration 	Details
 asf    	Success 	23:01:59 	       23:14:33 	49,6 GB 	47,2 GB 	21,8 GB 	       0:12:34 

Code: Select all

INCREMENTAL:

Name 	Status 	Start time 	End time 	 Size 	Read 	Transferred 	Duration 	Details
asf     	Success 	23:02:04 	      23:03:52 	49,6 GB 	469,0 MB 	159,1 MB 	        0:01:48 

Does this mean that the "Read" field is so low in the incremental backup because a smaller part of data are changed from the first backup (469.0 MB)?

Data transferred are so lower because they are compressed from read data?

Thanks

Correct, Veeam B&R performs incremental backups, copying only those data blocks that have changed since the last job run.

Correct, there is a compression and source-side deduplication too.
