Just a stab in the dark here to see if I can get some sort of help.

I have Server 2008 running with Backup Exec 2010. Whenever I attempt a simple full backup of our exchange servers information store, I receive the error during snapshot processing:

"Resources specified for snapshot do not have any valid data on them. Check if files were deleted or renamed."

I have googled for the last hour and looked up the Backup Exec 2010 manual and can't really get an answer that seems to shine any light.

It's really all the info I can provide, I hope someone can help.

Greatly appreciated.

Make sure you haven't disabled shadow copy or vss; make sure the disk isn't corrupt (chkdsk).

make sure the system isn't so busy that it can't respond too fast.

make sure you never install other vss-writers they don't play very well.

ie veeam/vmware guest drivers and backup exec client.

you using BESR or backup exec 12.5?

i've been using besr forever. it is for doing forklift dumps of the whole system only.

i use it to do full system backups, VSS aware every night. that is the only mode.



if you were to virtualize the system (ESX essentials $495) you could afford veeam ($500 per socket) and not have any issues with snapshots. vmware and veeam are excellent at snapshots. IIRC esxi 4.1 doesn't require double the disk space to deconstruct a snapshot any more. and has ramdoubler :) esx essentials+veeam is less than 1 server license of besr 2010 ;)

Does Veeam properly quiesce the system before it snaps for a backup? With BE you still need the the Exchange agent because the store can't be snapshotted (reliably and expect a restore to actually work) because the quiesce can't stop the exchange store access long enough (without corrupting it) to fully flush it to disk prior to the snapshot being built.


for OP: Most exchange issues I have found to be caused by store errors / corruption also.

yes it does; it also allows you in 5.0 (beta almost production) to reconstruct your systems using the full/incrementals and boot them off the backups without having to waste the disk space. ie you could boot every single backup of your entire network in a sandbox network environment and test it - str8 off the backups.

you know in case you really want to know if your "DR" plan is functional on a weekly/monthly basis..

but yeah it works reliably. you just follow best practice, use sufficiently fast enough storage - duh - and steer clear of thin provisioning on a sql server - and the VEEAM agent (not vmware agent) will quiesce exchange.

if your server had too little spare disk iops to snapsnot well that sucks. esxi 4.1 has brought some great enhancements to speed/size of esxi snapshots but it cannot defy the laws of physics.

You should always do a sql server backup, log truncate, reindex, check integrity as usual too. Just to be double-dog-sure.

I haven't had IOP issues. For whatever reason the snaps seem to lag just long enough to make stuff complain. I am not sure why. I am not alone out there either, there are lots of complaints about those kinds of errors if you try to quiesce. My solution was to not quiesce and backup the info via agents as well. So the VMDK backups are able to boot, then just restore the store to it.

Ok, bare with me as I'm trying to figure this out. It looks like it finds the information stores across our network/domain, but when testing credentials it returns "Resource not found"

I thought I knew enough to get this going (as we have another email server running an older Backup Exec without this problem).

Does this raise any other red flag on what's wrong?

Does "System" have access to the datastore? Try using a domain/exchange admin account to test creds with and see if it succeeds. I don't think "SYSTEM" has access to Exchange by default for security reasons.

I've tried multiple accounts including our domains Administrator one.



Also, thank you to everyone trying to help.

Just to clarify, the "System Logon Account" that's showin in the Backup Exec screenshot would be the account that the Backup Exec services run under.

Not sure what version of Exchange you're running...does this help: http://seer.entsupport.symantec.com/docs/288777.htm ?

Thanks for the link. We do have a backup exec account but it seemed to return the same result.

It seems as if it can't login to these other information stores for some reason..

Did you not buy maintenance with your licenses? It seems like you have the pre-reqs in place, assuming the agent installed all right on your Exchange box. If you are having this much trouble, I would call Symantec.

Alright, I realize I can't seem to provide enough info here for you guys to pick out what the heck is wrong so I'm gonna have to likely give them a call.

Either way I really appreciate the help, this forum is always awesome.

Thanks!

Alright, I'm bumping my post. Hope this is okay.

I got it to work, but I need further help on what I may have done.

I loaded up the Backup Exec disc and went to the trial software addons. I chose Backup Exec Agent and let it install. It said it was successful then it closed.

I reopened backup exec and it said it had an issue with credentials (our Administrator password changed a couple days ago, but long after the original problem started).

It also listed HDMG under this administrator account... I wasn't sure if it was listed as an information store or what, but I clicked start all services until BOTH listings showed services started.

Now I tested the resource credentials on the backup job and everything somehow tested successfully!

Now which do I eliminate as the solution? Installing the trial for Backup Exec Agent or resubmitting the new credentials?

I understand the latter sounds more obvious, but the password didn't change for the administrator login until weeks after I was having this problem.

Again thank you all very, very much for your help.

I didn't see it listed but did you purchase the BE Exchange Agent?
Unless 2010 is different or you're using SMB suite for Backup Exec, you need to purchase an Exchange agent in order to backup the IS...
