Jobs stuck indefinitely in Queued Status
We have had an ongoing issue for about 2 months now, and since we have had a clean build (3 times now) for Backup Exec 2012. We have opened numerous cases with Symantec to resolve this, and they claim the first time that HotFix 209149 (see http://www.symantec.com/business/support/index?page=content&id=TECH204116 ) corrects the issue. The issue is also noted by seeing Robotic Element errors stating that OST media is full and it brings the "virtual" slot for the PureDisk or OST storage device offline. Restarting the services in BE only makes the problem worse and causes a snowball effect whereby jobs constantly error in the ADAMM log files. Essentially, the jobs never can get a concurrency/virtual slot and they stay Queued forever. I have seen others on this Forum with this problem, and while the Forum administrator seems to mark them as "Solved", they are not - because I see the threads drop off with no resolution identified. Are other people having this problem? If so, how are you overcoming it? Once it starts the environment is essentially dead in the water because the jobs never start (they sit Queued forever) - save for one concurrency which for our size environment is only 1/4 the need we have. We use CAS and 4 MMS servers with 2008 R2 with all patches applied, PureDisk 32TB volume on each MMS, Data Domain OST connection to DD-670 OST with OST-Plug 2.62 (28TB), replicated catalogs, and duplicate jobs for optimized deduplication between MMSs. We run BE 2012 SP3 clean - we reinstalled with SP3 slipstreamed because Symantec said this problem could be fixed through database repair by them manually or by reinstall...we chose reinstall (even though they did offer to "fix" the issue with database repair). We chose reinstall to validate whether SP3 truly fixes the issue. It is clear to us it does not. We are looking for anyone else who has had this problem to report into this forum. Thank you, Dana

Client-side dedupe fails on 1 computer
Media server: WS2008 R2 SP1/BE2012 V-ray SP4 Remote servers: 1 physical WS2012, 2 virtual WS2012, RAWS installed and patched. Backing up at guest level to a dedupe device. Backups of the physical and one of the virtual machines complete successfully. The other virtual machine completes with this exception: Client-side deduplication is enabled for this job, but it could not be used. Please check this link for additional information: http://entsupport.symantec.com/umi/V-79-18273 The problem server has never worked with dedupe. I have followed the steps in http://www.symantec.com/business/support/index?page=content&id=TECH77683. Or, at least, the subset of them that apply to BE2012. No change. Restarted BE services on media server and problem server. No change. Disabled both firewalls; no change. Here is an excerpt from ADAMM.LOG that shows the 3 servers during the most recent BE media server services startup. (PRINT1 is the problem server.) ---------------------------------------------------------------------------------------------------- Host Name HYPERV Remote Host Name HYPERV Port 10000 User Id DOMAIN\svcBackupExec Vendor Id VERITAS Software, Corp.

Backup Exec Deduplication option
I currently have backup exec 2012 media server installed .It was backing up to a data domain device using OST plugin. I am using the 60day trial licenses(10 day Remaining ) However recently the deduplication option disappeared.As such no backups can be done to the data domain. On checking the windows services the following services were not runinng Backup Exec Deduplication Engine Backup Exec Deduplication Manager Backup Exec postgresql 8. I tried to start the services but got error 1053 postresql . I tried to start the the backup exec services (everything) but on restarting the services the deduplication services and the postgresql appear disabled and cannot be started.This is the case even on rebooting the server. "Windows could not start teh postgresql-8.3 service on "my server" Error 1053: The service did not respond to the start or control request in a timely fashion."

Backup Exec V-Ray edition licensing - two or more media servers and dedup
Hello, we have 5 VMware virtualization hosts with 2 CPU each and 10 licenses fo V-Ray per CPU (in proper tiers according cores count). But our network envirment are separated to two independent secure networks so 3 VMware hosts in one network with own management and other 2 VMware hosts with own management in other network. Networks are not connected each other (and can't be for security reasons). V-Ray licensing includes one media server and one dedup option. Questions: a) So having purchased 10 V-Ray per CPU can we use two media servers and two dedups (with 6 CPU in one net and with 4 CPU in other net) ? b) Or should we purchase separately 6 CPU for one network and 4 CPU for second network to allow two media servers and dedup ? c) Or can we divide our already purchased license (to allow use two media and dedup) ? d) Or there are general rule that one customer/company can only buy one V-Ray which cannot be divided (so such customer/company can use only one V-Ray instance) ? e) Or maybe there are optional purchase of secondary media server nad dedup option ? Thanks in advance

Backup Exec V-Ray edition deduplication limit 16TB vs 64TB
Hello, I found some articles on forum regarding this problem but I'm really confused by this two articles (one day difference in publication date) https://www.veritas.com/support/en_US/article.HOWTO23357 (telling that limit is 16TB) Publication 21.10.2015 https://www.veritas.com/support/en_US/article.000075730 (telling that limit is 64TB) Publication 21.10.2015 Or maybe 16TB is V-Ray edition specific limit regardless Backup Exec version Question: What is actual official limit for dedup option for Backup Exec 15 V-Ray Edition ?

BE2014 - Loading Media for hours during any restore (deduplication)
Hi There, Whenever i try and do a restore from my deduplication device (locally attached) from a recent backup, it takes forever to restore. For example today, i tried to restore a 70MB file, and it took over 1.5 hours. Most of the time the job was just stuck on 'loading media'. I logged a ticket with support, and got nowhwere. I logged a couple of tickets with support for a similar issue with backups, and got nowhere with that either. (Was told that it was normal behaviour) Is there anyone here who has tried to restore from a dedupe store? If yes, are you getting these issues? The server i'm trying to restore from is also a CASO Thanks in advance for any comments

The queried backup sets contain two backup sets with the same ID
Hi, After some serious disaster on BE15(latest patch), I managed to get the server running again. However I am facing a different issue. When I select the deduplication storage and select Backup Sets tab, I see "Load Failed... The queried backup sets contain two backup sets with the same ID." . This happened after I removed this member server from CASO environment. I checked the catalog files and they are present. I also tried the "Catrebuildindex -r" method mentioned at the post "https://www-secure.symantec.com/connect/forums/duplicate-backup-sets-same-id". This had happened a couple of times when the server was a managed server in CASO environment but after a couple of F5, I was able to see the Backup Sets and even start restores. Any ideas?

Duplicating backup sets from Managed Server deduplication storage to CASO deduplication storage
Hi all, After my Backup Exec 15 (latest patch and sp) server failed and returned back to life, I installed another BE15 and enabled CASO (Central Administration Server Option). Now I need to duplicate some of the backup sets that reside on the old server (now managed server) to CAS. Both have deduplication option enabled and have dedup storages configured. Both can perform backups. When I browse old server's dedup storage and select the needed backup set and select duplicate option, I see the new server's dedup storage. I select new server storage and start the process but it is stuck on "Ready; Backup Exec Server not available" on the job monitor tab. This is the screenshot of the job: And here is the frustrating outcome; I have enabled private cloud out of despair on both server and ofcourse it did not do any good. Anyone have any idea?
