In my test environment, the Acronis reporting space does not match the actual disk space.

This was a freshly formatted partition with only the vault created on it. I ran full backups of 4 workstations and 10 or so incremental.

I have manually compacted and indexed the Vault.

Am I incorrect in that assuming the "occupied space" should reflect the disk space used?

Hi Murigar

Thanks for your post,

Going on the information provided it looks like all is going well and you are getting good compression as well as deduplication ratio's.

Basically when Acronis reports the "Occupied Space" this is the total amount of space that is being consumed on your backup server (Storage Vault) AFTER compression and deduplication is performed so it should generally be less than what you have backed up.

In your vault you can enable a new heading in your vault called "Original Data Size" by right clicking on any of the current headings in the list view of backups and enabling the required headings. This will show you for each backup what the original data size of the backed was.

In your screenshot you provided you can also refer to the "Backed up data size" field which is currently reporting 380.5GB, this is actually the total amount of data that is being protected (this will included Full, Differential and Incremental backup data in total before any compression or deduplication is applied).

I've just noticed the folder structure (image) you posted is that of your vault and is allot larger... Acronis will process/compress and index backups which can be time consuming and I/O intensive, you might find there is still a compacting task or similar still running on your storage node/vault perhaps?

If not it might be good to get onto Acronis support to check into the vault in more details...

P.S. I would also suggest you check into the deduplication best practices to ensure the steps recomended have been taken to help reduce the chance of delays, overheads...etc.. which is important when running deduplication:

Hope this explains things a little more.
Enjoy!
