ESX - CA Backup failed!!!

alize77 · ‎09-06-2007

I follow the steps mentioned on CA docs to install and configure the Linux CA but whenever I tried to backup the VM, it will indicate "Failed to Open .....". It can't seems to open the vmdk-flat file and I thought the pre & post backup script from CA is use to ensure that the backup is able to run and create a snapshot of the VM while it's running.

1) Install Linux CA on ESX server

2) Copy the script file from CA media and edit the uag.cfg file

3) Open port to allow 6050/6051, tcp/udp, in/out

4) Add machine in CA Backup server

As I'm new to this, hope that someone can advise me if I miss out any steps. Thanks in advance!

Check if you have given execute permissions to pre and post perl script files on ESX Server.

If not, you can do so by running the following command in CA Universal Agent folder (default path is /opt/CA/BABuagent)

chmod 755 *

Let us know if this resolves your problem

Thanks,

Vivek

Backup Operation Incomplete.

On my ESX, i got the msg "Can't use an undefined value as an ARRAY reference at /opt/CA/BABuagent/pre_backup.pl line 168, <$backup_list> line 6."

I thought the pre & post backup.pl file from CA work without the need to do any changes!

PerryWhittle · ‎09-12-2007

you need to give the Arcserve agent rights to read the VMFS partition directly like so

grep vmfs /proc/mounts >> /etc/mtab

just out of interest what does your uag.cfg file look like?

BTW did you install manually or using the CA scripts (i found they failed)

PS please award points if you find this useful

Please rememeber to award points if you found this helpful or correct

alize77 · ‎09-13-2007

I have already ran the grep vmfs command prior the backup. In my uag.cfg file, I have entered the following line:

-P 2

-Prebackup /opt/CA/BABuagent/pre_backup.pl

-Postbackup /opt/CA/BABuagent/post_backup.pl

I copied the CA script from the CA SP3 media into the BABuagent folder.

Thanks!

alecapella · ‎01-04-2008

I have the same problem in same situation you are. I'm working to try fix it while wait some tip.

Thanks

Alessandro

tbrouwer · ‎01-04-2008

I have had these same problems, and have also fixed them.

First step is to change the -P 2 to -P 0 .

As noted in this thread make sure you have permissions for all the files needed.

If this does not work you will need to upgrade the agent ... I have the upgraded agent if anybody needs it.

Just to verify, you can backup the VM when it is switched off, correct?

alecapella · ‎01-04-2008

Hi,

I can complete the backup if the virtual machine is turned off.

I changed the P parameter to 0. When I turn it on, no way! It does not work.

Do you have a new agent version? Where can I get it?

Follow my configuration parameters

-b 65536

-c 50

-s 65536

-P 0

-Prebackup /opt/CA/BABuagent/pre_backup.pl

-Postbackup /opt/CA/BABuagent/post_backup.pl

Thanks

Alessandro

tbrouwer · ‎01-04-2008

I attached a zip with the updated files. Check the readme.txt in there and make sure you have all permissions set for each file ( I just did chmod 777 filename.xxx in the meantime just to get it working). Let me know how that goes!

tbrouwer · ‎01-04-2008

Here is the actual link I got from CA tech support:

http://supportconnect.ca.com/sc/solcenter/sol_detail.jsp?aparno=QO87405&os=NT

It doesn't necessarily look like it would help our issue, but it did solve it for me.

tbrouwer · ‎01-04-2008

Oh and one more thing...

Once I got it working with the updated agent, I was only able to backup one VM per job as the second/third/fourth/etc ones would fail. That when I changed the -P 2 to -P 0 and it solved that problem.

alecapella · ‎01-04-2008

Thanks, I'm going to make a test right now!

alecapella · ‎01-04-2008

It's working now!

I've just update the files with the zip you posted and it is working fine now!!!

Thank you very much! (Now my Friday's beer is certain and will be better

tbrouwer · ‎01-04-2008

Great, on that note, I better tip back a Friday beer as well!

Just a question, was this on an esx3.5 host? I am currently struggling to get the CA backup agent to work on my new 3.5 hosts

alecapella · ‎01-04-2008

Hi,

No, my system is running on ESX 3.02 (with all patches)

Thanks!

JasonInJersey · ‎01-04-2008

We're having similar issues on our 3.5 ESX host. I updated using the new scripts that were posted here (THANKS!!) and we get a complete backup. But after a test restore i still can't get the VM to fireup after i re-add to inventory. It just gives "File not found" error in VIC. Looking at the log for the VM itself on the host i see this in the vmware.log:

Yet the files exist. And are in the correct paths etc. Anyone get this issue?

myaeger · ‎02-04-2008

I am also experiencing this problem. I am using the same config files that you posted, as well as using -P 0, and have given full file permissions.

So reading your posts, it makes me think I have to upgrade the agent. I currently have 11.5 sp3 on the backup server, but the 11.5 sp2 client on the ESX server. So it sounds like maybe I have to upgrade the ESX client to 11.5 sp3?

Do you have those files and/or instructions for that?

Thanks,

Mike

Please disregard - turns out I had some bad syntax in my uag.cfg file. It's working fine now.

alecapella · ‎02-07-2008

Hello,

I´m posting the files I used on linux side.

Inside the zip file, there is a file called readme.txt with instructions.

Thanks

Alessandro

tbrouwer · ‎02-07-2008

You know what, I have that same problem. In a pinch I was able to edit a line in the .vmx file for the virtual machine and got it to work. I will be re-visiting this today and see what I can find. Alecapella, are you able to restore machine from backup successfully and add them back into inventory without any problems?

JasonInJersey · ‎02-07-2008

I wound up calling VMWare support and they told me that the fix was to hand edit the vmx file.
