Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I have a very specific question. It is my first question here so I hope to be doing it correctly.

I have a Quantum DXi 4510i that a client is using for the backup solution. This appliance is interesting because do deduplication of data. The problem is that when the disk gets to a threshold limit (550GB of free space at disk) enter into a throttle mode and the data ingest is being done veeery slowly (around 100k/s) the regular speeds are around 70MB/s!!

There are tw obvious solutions from my point of view:

1) Increasing the disk space 2) Deleting some old backups

The problem with the first option is that it will take a looot of time to be done by the support so meanwhile we need a workaround solution. This workaround solution is deleting some backups. But this is taking a lot of time because before of deleting old backups they need a confirmation from the HQ. Meanwhile they have no real backup of their servers...

That is the current situation and I have think of another solution that is changing the threshold limit but I cannot find the option in the configurations menu. But googling I read it is possible to change the threshold value from 5% to 95% this would be great in order to have backups a few more days till the OK from the HQ arrives.

Sorry for the long message, thank you all by your time!!

This is very specific, I suggest calling their support line. –  Lucas Kauffman May 1 '12 at 7:39

Does DXi4000 provide file level access to the backups? If true you could just move the old backups away from the appliance. –  Dmitri Chubarov May 1 '12 at 7:42

It is very specific and we already have an open case with the support line but I can't believe it how slow are they replying. I don't know for the rest of the people but for me backup is a key point! –  zordor May 1 '12 at 7:59
    
And yes Dimitri we can access directly the data but they are deduplicated so they are around 35TB and we don't have in the client that amount of disk. I think the main problem here is that nobody in the client side is taking seriously the problem :S Anyway thanks for your help, let's see... –  zordor May 1 '12 at 8:01

According to Quantum you cannot change that so the only solution was to upgrade it with more hard drives or delete old backups (we did that one).

interesting... good to know that you still need X amount of scratch space to land a job –  SpacemanSpiff Dec 18 '12 at 2:54
