Reverese Incremental

Veeam Logoby lukejf » Wed Mar 29, 2017 1:33 am

Hey Guys
Just wondering, how much data is transferred over the network during a reverse incremental, Incremental backup. If looking at the console is it only the transferred data or is there other network traffic based on reading changes etc.
The reason i ask is we are moving to a datacentre with a 1Gbps network connection. Whilst we are replicating over all the VM's we would like to keep our veeam server at our office backing up to tape. Just trying to work out if we are going to have backup delay issues. We are currently running all our servers on a 1gbps link now however the bottleneck will change from switched ports to a single link
Cheers

Hey, Luke.

Here is a short explanation of job statistics:
Data size — total size of all VM disks processed by the job.
Read — amount of data read from the datastore by the source-side Data Mover Service prior to applying compression and deduplication.
Transferred size is the amount of data the backup job transferred to the destination.

Amount of transferred space is same for forward and reverse increments. Additional metadata should not be an issue.
Thanks!

Dear all
Hi

i read 3 items in veeam report and understand this :

Processed : i understand this is the size of data that is on the disk and veeam read that for example if my dizk size on vm is :150G and for processed show : 50G means just 50G of vm disk has data and 100G is free

Read : Data size had to transfer to backup repository before compress and deduplication

Transferred : Total data size that has been transfered to Backup repository after compress and deduplication

Your post has been merged into existing discussion, check the explanations provided above (Nikita talks mostly about job statistics, but same principals apply to daily report) and ask additional questions (if any left). Thanks.

Processed is based on the total size of all VM disks added to the job. So during the job it is the amount of actually processed data, which in the end of the job should be equal to the total provisioned size of all VMs. Read is what actually read out of these processed data, since there are empty blocks that are skipped, etc. You're correct about the transferred count.

thanks
but not clear answer . can you say me
1 - for example my vm disk size is 100G but 60G of my vm disk has data now process will be show 100GB or 60GB ?
2 - read is total data transfered before compressed
3-Transferred : total data transfered after compressed

1. It should be 100GB
2. Correct
3. Correct

Amount of data read from the source VM by a backup proxy
Amount of data transferred over the network from a backup proxy to a backup repository
