2003 file PST and MPEG files considerations Avamar 5.0 sp3

I am am having issues with backup times trying to backup 700GB of file USER data made up of MPEGS and PST files.. I have adjusted file cache to about a -6th and not using it all p cache has been reduced to -32 . It the charactistics of these too type of files need more p cache or f cache..

It takes about 20hrs to back up if I turn on overtime on the back up.. with defualt cache settings.

Thanks

Hi Fred,

Performance is one subject much extensive...

To avamar use new configurations of the f_cache and p_cache you need to remove the files of the client (program files/avs/var/f_cache and p_cache) and then avamar will create the files in the next backup, next backup will be slow why considering how first backup, but the second backup should be faster...could you use cache-prefix too but the result will be the same.

Make sure if you need change the cache parameters, in the log of the client you see how much the cache is using and the maximum released for growth.

See too how much million files he is saving, in the best performance he save 1 million per hour.

Put the log of the client for us see what can be done to improve performance.

Could you configure the avamar to connect to all nodes too for improve performance, but this only after check items above.

Hope this help you.

Regards.

Right now we are rebuilding the f_cache's about 40gb per hours with 700GB to be fully backed up.. I will have a better idea but looking at 20 hours and overtime is turn on..

Forget how much GB you have to backup, think in million files, dependence of performance is how much files you have to save.

Example in my customer:

Client A = 3.5TB to backup
500.000 files
Backup duration = 40 minutes or less

Client B = 750GB to backup
10.000.000 files
Backup duration = +-13 hours

If those configurations i've posted in the first message don't solve i think better you open the case with support EMC.

Re: 2003 file PST and MPEG files considerations Avamar 5.0 sp3

Be carefull with parameters of the f_cache, look the he is using only 88.0MB and he grow *2 then the next value will be 176.0MB (see the log 88 of 767Mb).
Maybe is using swap memory of the client and decreasing performance, what value did you put in the file cache and hash cache? How much memory have this client?

Log:

Cache update complete C:\Program Files\avs\var\f_cache.dat (88.0MB of 767MB max)

Please put the entire log...
