Backup Central

Hi,
I am evaluating FlashBackup-Windows. I am backing up a 1.8TB Volume, with millions of 1kb files and via SAN, its taking 3 days.
During a quck FB-Windows Test Policy, I got this down to 7 hours. However, 2 questions:-
1) Not been able to test, but is there a downside to restore times for this type of volume
2) I read a Technote, that when restoring FB-Windows, certain files dont get restored, like Outlook .pst files. Now, I cannot find the Technote, but I wondered if that was fixed in 7.0.1
3) The Server has 5 volumes, but it does not look like you can "stream" jobs. Does anyone have a policy where it contains multiple volumes for a single client. And can you improve the performance? I could Multiplex I guess.
Thanks
Regards
Simon

To improve restore performance I was told by SYMC that I would need to enter the individual ESX host that this VM lives on into the Credentials > Virtual Machine Servers section. This will bypass the V-center host and your media server will send the data directly to the ESX.

Its an admitted bug in the NBU architecture.

Hello Simon.
I can answer you only to the first question.
Unfortunately the file restore of a single file can take as long as a full restore, as netbackup has to read the backup to find the file. If the file is in the beginning of the backup, then it is fast, else….

For the 3ed, you can always create multiple policies.

Hello Simon,
For 2nd, there was an issue late in 6.5.x with pst files with high data movement (mail copy, deletion etc.) during snapshot time. These pst files were restorable but some of the mails were missing which were moved during snapshot time. It’s fixed with 7.0 onwards.

Hi Stefanos
Thanks .... but in a DR scenario... where you would have to restore all the Data, would FlashBackup-Windows be quick?

My testing with FlashBackup here has generally resulted in faster volume restores than volume backups. This is dependent on many factors, including the activity of the disk / raid group during backup / restore. Generally speaking, my raid-5 arrays write data much faster than they read it. Assuming your disk reads and writes at the same speed (unlikely) restores will take just as long as backups, because you are writing out the bits in the same order you backed them up. You may want to review the documentation on FlashBackup, as restoring the entire volume is not the same as restoring “all the files.”

Hi jonathan
I would like some real world advice on this then. Because if I understand correctly, although I have 4 volumes to backup as FlashBackup-Windows, I dont see any options to do "Streams".

So do you have Servers that have multiple volumes? Do you create seperate policies, or just group them together and maybe Multiplex them?

The “stream” options are the same on a Flashbackup policy as they are on any other.

Policy > Allow Multiple Data Streams – creates one backup job per item in the file selection list
Media Manager Storage Unit > Multiplexing / streams per drive – number of jobs that can write to a tape simultaneously

I don’t multiplex because I write to disk. I use the multiple data streams option to break the backup into multiple jobs. That way, if the e: fails (for example) the job continues with f:, g: etc… I also limit the number of jobs per policy to 1, so the e:, f:, g: etc… do not run at the same time. I limit the jobs because e:, f: and g: may be on the same raid group, in which case they share the same disk performance.

you can put each volume in serperatly and the job will spawn off a backup for each volume.

Example:
\\.\D:
\\.\E:
\\.\F:

the job will spawn off three backup jobs one for each volume.
