Veeam Backup VM size

[nelson963]

Hi,

Would like to check anyone encounter issue in this scenario.
a. VM guest has provisioned space approximately 130GB, used space from disk management total up approximately 50GB.
b. I m using Veeam Backup and Replication 7.0.0.871.
c. I have done recreate the backup job and rescan the backup VM size, repository.

Right now, everytime i see the Veeam report, the size VM is 130gb, read size is 125gb and transferred size is 50gb. Can anyone tell me what's went wrong?

Regards,
Nelson Ng

Hi Nelson,

Processed — 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.

Looks like nothing went wrong. What`s the size of backup file&? Thanks!

Hi Nelson,

If you want to reduce the size of full backup, then you need to run an sdelete command inside the guest OS, as most likely you have already had some data written to these file system blocks and then removed them. Please check out this topic for more details > VBK Size - NTFS (4K) vs EXT4 (64K)

Thanks!

Hi,

Appreciate your suggestion on this issue. I tried the steps below:

1. Copy the sdelete into vm guest and ran the sdelete on C drive, D drive and E drive.
2. After the three execution of sdelete on the different partition, Vcenter shows maximum size disk in host storage views for that particular vm guest.
3. Tried vmotion the vm guest into local disk but the vcenter still showing maximum disk. The used space same as provisioned space but in actual disk management only shows 20% data usage.
4. The vm guest is windows server 2003 x86. Three partition C, D, E drive.
5. My vmware version is ESXi 5.5

What should i do next?

Did you vMotion this VM or used storage vMotion?

Does the storage you've migrated VMs to use a different block size?
