Indexing taking a long time
I have had tickets for this in the past, and this has never been resolved to my satisfaction.
My Vaults are stored on a CIFS server and the indexing tasks take a *very* long time to run.
My Acronis server itself is an 8 core xeon and has 16Gb ram ... during the current index task it's using less than 1% of CPU and about 6Gb RAM ( mostly used by SQL ).
io stats on my CIFS server show very low read speeds during the index tasks ... ranging between 512KB/s to 3.50MB/s. Yet I can copy files to/from that CIFS server at several hundred MB/s to the acronis server ... so I know that it's not the performance of the CIFS server that's causing the problem.
The acronis server shows about 2.5MB/s being written to the volume that contains the vault database... again this is capable of much faster.
The current index task is after backing up a 800Gb volume to a dedup enabled vault. It has been running for 14 hours and estimates another 5 days and 7 hours to go.
This speed is totally unacceptable... how do I get it to go faster?

Apparently it failed at some stage with the following error ...
Also ... Given that I pay a premium for support, I would expect some response on here?

I to have been recieving the following error each time the indexing task runs.
It would be nice if one of the Acronis Maintenace personal would take a look into this and offer a suggestion on how to fix the problems.

I would like to see how this problem plays out. If its been resolved Yana can you post it?
At the moment I cant see how you can use this product if you have more than a TB or two of data, so I think its important to make it public. I see other threads on the subject but they go nowhere as far as I can see
Thanks
Steve

Hello all.
First post in the forum, but thought it may be important enough for other people having this same slow Indexing problem.
THE PROBLEM: INDEXING IS PAINFULLY SLOW
I had the exact same problem. I backed up a single XP machine into the XP Dedup Store I created on a Centralized vault. The vault was created on a QNAP NAS, Raid 5. I had to enable NFS access for Acronis to see it.
Indexing was taking hours for even a single machine that had an 80Gb "C" drive. No other drives where backed up, just the SYS VOL.
OK...after much searching and investigation I think the problem is SOLVED. At least my Indexing completed in record time, and all Indexing after the initial one are also completing.
THE SOLUTION:
Ok, Acronis may have fallen down a bit on this one as it is a small fix that has BIG implications!!
It has to do with the naming convention in the UNC path to your Vault.
On my QNAP, I created a share "Acronis", I then created a sub-folder labeled "WinXP". (as I will have different dedup vault for diff O/S's).
Back in Acronis, when you create the Vault, your are asked to point to, or browse to the share folder. Pretty simple.
However, this is the very place where Acronis falls down.
I choose “Network Folder”
Browse to the Host where my share is
Once you start highlighting your Host, then the share etc, the lower “PATH” box gets filled in accordingly. Watch that “Path” box as you drill down and find your folder.
You will notice Acronis making changes to any Capital letters you may have in the path.
If this is the case, that is the culprit to the problem.
My example:
\\HOST\Acronis\W2K....... Acronis takes my UNC path and makes a slight change...shown here
\\host\acronis\W2K
You will notice that the Capital letters for my “HOST” name, and the “Acronis” root folder has changed, but curiously, not the Subfolder.
Screen Shots attached.
If this is happening to you, check the UNC path name for upper/lower-case letters, as it may have the same effect it had for me.
I had to delete and recreate the vault, but this time before committing the path, I "Upper-cased" any letters that ABR lower-cased.
All is working great now.
Such a simple fix for such a frustrating error.
I hope the next release has a bunch if bug fixes, as this version leaves a little to be desired.

@Howard Hood
Short question about this. How fast is now your indexing? I'm trying to index 1.4TB and it is impossible :/. The task fill up all RAM of the server and needs days to end.

Hi Stefan,
Sorry for delay. Just been installing a new NetApp Storage Array so we can move off the QNAP.
I currently have an indexing task running on my Dedup Store. Total size is now at 494Gb which consists of 27 archives and 38 backups.
That is the dedup size. Original data size is calculated @ 835.9Gb so about half of yours. Dedup space savings is approx 59%.
My Dedup Store is 268.1Gb
Indexing has been running for 1 day 21 hours now @97% with 1 hour 24 min remaining.
Although it may seem to be taking a long time, it should complete with out errors. The problem I was having previous to me fixing it was the indexing continually failed to complete. Or was taking so long it wasn't worth the wait. Be SURE that you are only One backup and then have the indexing on that single backup before adding any additional backups to that store.
When I did the FIRST Dedup on only ONE backup, it ran very fast, cannot give exact numbers as i thought it might run as before, yet when I went back and looked about 3 hours later it was almost complete.
In the last 30 min while attempting to write this post, my time remaining is now 56min 33sec. So in 30 min it has progressed considerably. Now at 98%.
I am just so happy that its working albeit it's still not as fast as I would like.
One final note, while my indexing is running my cpu utilization is under 5%, Ram is only using 66Mb, proccess that is running is: "StorgaeServer.exe"
Tks
Howard
