Understanding replication job progress information

[gparker]

Thanks again tsightler, you've been of invaluable help

I will go ahead and configure a source-side Veeam proxy/repository server and will let you know what improvements I get when I kick off replication.

Many thanks,

George.

Hi tsightler,

You're a genius

I configured a Veeam proxy and Repositiory on a VM at the source site, reconfigured the replication job to use these setting and an 80GB VM whos seed on the target side is over 2 weeks old took 20 mins to complete the replication

Thanks again.

George.

In the job reports..could you explain difference between READ and TRANSFERRED mean.
Does Transferred mean the daily change rate?
Thanks!

What do these fields mean (looking at the report for a job)
1) Total Size - This appears to be total of VM disk provisioned size.
2) Backup Size - Is this the ("Total Size") - (free space) of the VM disks?
3) Data Read - Is this the amount of changed data as reported by CBT?
4) Transferred - I assume this is the amount of data transferred to the repository after dedupe and compression?

Example Backup job contains two small W2K3 VM's each with a 5GB disk (thin provisioned). Job report of the initial (full) backup shows :
- Total size 10GB (2x 5GB ... that's understandable)
- Data read 3,5 GB (which is the amount of data actually used by the VM's ... also makes sense)
- Transferred 1,8GB (so de-dupe and compression reduces 3,5GB to 1,8GB if I understand corerct .. this is approximately a factor 2)
- Compression 2,0x (hmm .. that matches what we see looking at transferred vs data read)
- Backup Size 1,2GB (this is what is actually used on the repository side for storing the backup data ... so some deduplication is being done, but ...)
- Dedupe 4,5x : This is something I don't understand. How is this number being calculated ? Anybody any ideas ?

Andre, please also see this topic for dedupe factor explanation. Thanks.

[aalders]

OK ... the explanation makes sense, but the numbers did not match. I just upgraded my 6.1 installation to 6.5 and using the same backup job data the report now says that the dedupe factor is 1,5x (in stead of 4,5x with version 6.1).
This makes more sense (transferring 1,8GB and storing 1,2GB matches the dedupe factor of 1,5). I'm happy now

can any one explain to me the veeam backup job session report? I have a full backup of a SQL server with total used space of 300 GB, but according to the report it states: Read 95.5 GB, Transfered 65.6 GB. Does it mean my whole sever was not backed up?

[v.Eremin]

Does it mean my whole sever was not backed up?

Nope.

I assume that it was an incremental run and CBT mechanism was definitely leveraged. If so, VB&R tried to read only the blocks that were reported by CBT mechanism as changed ones, also performing additional activities, like filtering out overlapping snapshot blocks, zero-data blocks, blocks of swap files, etc. Later the “read” data was compressed and transferred to target location, thus, there was a difference between read and transferred values.

Thanks.

Greetings Everyone,

I am looking for a greater in-depth explanation on the job process summary located at the top of a backup job. As seen in the screen shot below, I am trying to understand the data column. Can the collective review my explanations and make adjustments where necessary.

Processed: The amount of data the job has scanned in the VM
Read: The amount of data that is unique
Transferred(x.x%): The amount of data sent over the wire. The percentage is the rate of inline data deduplication.

Much thanks to everyone

I've heard that eventually the user guide will be updated to include that level of detail.

In the mean time, please see my post here.

Hello guys,

I have a doubt about a job of replication.

My VM has a size of the 56GB, in job log, the size of 'Transferred' is 32,5GB (1,7x), what does that mean?

Other issue, in job log, the "Swap file blocks skipped: 1,6GB" what does that mean?

[foggy]

Daniel, you can find more detailed explanation of the counters in the thread above.

Also please review this user guide section for an answer to your second question.

Thanks.
