RALUS on AIX 5.3 horribly slow

[Kane]

Good morning, I'm hoping someone can help out. I'm running BE 12 (upgrade from 11d via LiveUpdate). I have an AIX server that has the version 12 agent on it (it was also doing the same thing with agent 11 and BE 11d)

Whats happening is that I'm getting extremely slow through put on the AIX box.  any other host runs at about 300 - 500MB/min  but the AIX box drops down to 30MB/min or less. If I run a backup only of the AIX box it starts @ 1MB/min and slowly climbs to about 30MB/min.

We have tried the following suggetions with no significant gains in speed:

Can anyone please help me out with this? I'm not an AIX guy, so all suggestions will be passed along to the fellow who does the AIX support...

Thanks in advance.

Does anyone have any suggestions? It's taking almost 20hrs to back up 20Gb from the AIX box.

We are seeing the same exact issue.   Not that this will help you out at all but it seems to be tied to backing up a large amount of very small files.    When we backup large files on the AIX box by themselves we get the typical 500 -750 MB/MIN.   When we go after everything which includes the small files we only get 20 MB/MIN.   Please let me know if you've found a resolution.

Hi Greg,
No resolution as of yet.

Kane,

This is an issue we are currently looking into.  We have had a number of cases opened for this issue.  Please watch the announcements for updates to this issue.

Thanks,


Ben

Installed SP1 for Backup Exec running our fist backup with it today an it seems to be running a lot better.

Any luck on this?  We are experiencing the same thing on our AIX systems.  I am sure it is about the large amount of small files that need to be backed up on one of our servers, since the few large files on the other server seem to backup fast.  SP1 doesn't seem to have helped for me.

hi everyone,

This is a known issue we are working on. Our backline is still researching on this environment.

The backups are faster for large files. However, if you backup large number of small files, it is very very slow.

We appreciate your cooperation.

I'll try my best to use this thread to update regarding the same.

Thank you.

Regards,

-Arif.

[Kane]

That would be fantastic, thank you!

Just throwing in my 2 cents to say we're seeing the same thing (and to watch this thread for updates).

A lot of the data files on the AIX server in questionare larger (hundreds of MB to a few GB each) and they back up at a very high speed.  But any time it hits a directory with many smaller files (e.g. /usr), performance drops to as low as 1MB/min.

Anser,

Just curious if there is any update on this. I haven't seen any announcements about it.

Thanks.

It has been a few more months now and haven't seen any announcements about it.

I am also seeing this behaver on BE v11d, on both Linux RH5 and Solaris 10 RALUS client v7170.51.

Any word at all? Is this fixed in v12.5?

-Thanks

[Kane]

I've all but given up on this subject. We are still running 11d and it is still an issue. Our daily backups take 2 days to complete.

Would love for a solution to this...

[Anser_Arif]

Hi all,

I've an update for Backup Exec 11d.

Make sure Backup Exec is updated with SP3: http://support.veritas.com/docs/303199

After this, we need to install Hotfix 51 on the media Server: http://support.veritas.com/docs/308362

Further, another linux based hotfix needs to be installed on the Linux box.

For AIX, refer: http://support.veritas.com/docs/308369

For Linux (32-bit), refer: http://support.veritas.com/docs/308364

For Linux (64-bit), refer: http://support.veritas.com/docs/308365

For the hotfix of Linux based installation, copy the *.gz file on the Linux box and extract it using

tar zxvf <filename.gz>. Then, run the ./installraluspatch.sh

If tar zxvf doesn't help, you may run gunzip <filename.gz> and further use tar xvf <filename.tar> to get the installer.

Please keep me posted here if this helps.

Wish you all a very Happy New Year

Hi Anser,
Thank you for the quick response but unfortunately the Hotfix 51 did not help Linux RH5 or Solaris 10 (I do not run it on AIX). I did everything you said in your post back in September when the Hotfix came out but I still have the slow throughput when backing up many small files and/or deep directories issue.

We are on 12d, does the fix apply?

[Kane]

Hi Anser, we have had SP3 and hotfix 51 applied for sometime now with zero results. We are also looking at upgrading to 12.5. is this issue corrected in 12.5? If not I don't want to waste the money.

Thanks

[PB_2]

We are also on 12d and still have this issue backing up our AIX server.
