Defragment & compact full backup, how much free space?

Veeam Logoby HendersonD » Wed Sep 21, 2016 7:04 pm

I have my backup job set to "Defragment and compact full backups" once a month
I have my backup repository set to "Use per-VM backup files"
My repository is 8TB with 5TB used and 3TB free

How much free space does the defragment and compact operation need?
Does it need as much free space as what is currently being used (5TB)? In this case I would need to increase the repository to something greater than 10TB
Does it need as much free space as the largest VM that is backed up? My largest single VM is 1.8TB

Hi,

It needs as much free space as the largest VM's backup, 1.8 TB.

Thanks

In v9.5 it will require as much free space as all full VM backup files consume, since v9.5 will introduce parallel compact operations for the backup job (backup copy compact is already works parallel in v9).

Currently I am consuming 5TB of space on my backup repository. So to prepare for the hopefully soon to be released v9.5 I should increase this backup repository to 11 or 12TB, correct? This is needed since v9.5 has parallel processing for the defrag/compact operation

This will be the upper free space estimate, in fact it might need less, since smaller VMs will be completed and release space faster.

Since this is a little hard to predict and a dynamic process, to be on the safe side I will make this backup repository 11TB. I have two very large VMs, both file servers. If the parallel defrag/compact process happens to take place at the same time for both of these and a few other VMs then I want to make sure I have enough space.

How many parallel defrag/compact operations can take place at once?

According to the repository concurrent tasks limit.

I backup about 40 VMs and my backup repository is set to 8 concurrent. To be on the safe side I will increasing this backup repository to 11TB so I do not have to worry about running out of space during defrag/compact once v9.5 is released.

Any word when 9.5 goes GA? We are also a Nimble shop and I am looking forward to the integration

Hi,

Do i need to configure anything for parallel compact operation or it's done out of the box?
