Kate An excellent pointed Email, and again exactly how my setup is configured (with a few more volume pools, but its manageable and works) Regards Simon Weaver 3rd Line Technical Support Windows Domain Administrator EADS Astrium Limited, B32AA IM (DCS) Anchorage Road, Portsmouth, PO3 5PU Email: [EMAIL PROTECTED] -Original Message- From: Greenberg, Katherine A [mailto:[EMAIL PROTECTED] Sent: 26 April 2006 18:08 To: veritas-bu@mailman.eng.auburn.edu Subject: RE: [Veritas-bu] Volume Pools [recommendations please] OK boys, (and girls, altho we seem to be generally keeping our mouths shut on this one!) to summarize... 1. Yes, you can have multiple retentions on a single piece of media. We have established this at least 4 times on this list. However, it is not recommended to do. (unless your life sucks like Jonathan's here) 2. Volume pool configuration is really up to the individual shop. PERSONALLY, I do not use the NetBackup pool for anything but catalogue tapes. If you opt for the 1 POOL configuration, your best bet would be to make an alternate pool, set your policies up to use it and then throw everything into it. 3. If you opt for Multiple Volume Pools, best practice is to utilize a SCRATCH POOL and let NetBackup divvy the tapes up accordingly. Post-4.5, if a tape starts in SCRATCH, it will be returned to SCRATCH once it's de-assigned. I, personally, use Volume pools based on the Environment which they back up (Corporate, Web, etc.). I also use volume pools for duplicated tapes. I support a 250 + TB environment and this works well for me. Breaking things out and micro-managing this application is really not necessary. As long as it's set up intelligently, it will self-manage, unless something in your environment breaks. ~Kate -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Martin, Jonathan (Contractor) Sent: Wednesday, April 26, 2006 12:56 PM To: Paul Keating; veritas-bu@mailman.eng.auburn.edu Subject: RE: [Veritas-bu] Volume Pools [recommendations please] Sorry to call you on this one, but you CAN have multiple retentions on one tape.

Unless you have mix retentions on media set which i think everyone has agreed is a bad idea. Agreed...but mixed retentions has nothing to do with multiple volume pools. You can have 10 different retentions and only 1 volume pool, and you will not get two different retentions written to the same media. A single volume pool does not equal mixed retention on one media. Your description below uses 4 tapes ( if one tape per backup is used ) which are all associated to the same volume pool. But each tape has a different retention.

This script will get you the tapes in the jukebox for a particular

#robot parameters
if [ -s /tmp/robot ];then
ROBOT=`cat /tmp/robot`
else
ROBOT=`/opt/openv/volmgr/bin/sgscan | awk -F: '/P1000/ {print $1}'`
echo $ROBOT /tmp/robot
fi
ROBCMD=$VMDIR/tldtest -r $ROBOT
#Get Jukebox Inventory
get_jb_inv()
{
cp $JBINV $JBINV.old
echo s s | $ROBCMD | egrep slot|Barcode $JBINV

#Command finds scratch tapes

$1==pool name $2~/^ *'$SPname'$/ {print pn}'`
# Note: vmquery col 1 is tape number
# col 3 is tape type
# col 12 is poolname

## This works
## For NB 3.4 00/00/00 needs to be 00/00/

I don't know why you're getting that error, but it must be specific to the raw backups. In my environment, I have several clusterseach has a shared data drive, and each has a system particion and a couple others. Example Cluster_node_1: / /u /node1 Cluster_node_2: / /u /node2 There's a policy that backs up cluster /data, which is the shared resource, backed up via a virtual name/IP, but I have another policy that backs up the physical nodes. The backup selections list has the following: / /u /node1 /node2 The client list has: Cluster_node_1 Cluster_node_2 There are no exclude lists on either node... /node1 gets backed up on the node1 backup, and /node2 gets backed up on the node2 backup. Never get a 71. Works a charm...so I would venture to guess it's either specific to the raw backup, or it doesn't like that you've specified and exclude list for a fs that doesn't exist.

Re: [Veritas-bu] RE: [Veritas-bu]Status 71...was: Volume Pools [recommendations please]
Yeah i had come to that conclusion myself. The only worrying thing was i didn't want to leave it to chance that the raw partitions wouldn't appear on the client which didn't normally have them. Its all san storage connected see and if someone adds a new volume to the client with the same device path ( i know doubtful ) it may be being backed up when i dont need it to be on that client. Think ill leave the exclude list in place and put a known good small file in the stream which contains the raw stuff. Thanks for this. Dave [EMAIL PROTECTED] wrote: OK - I just tested this. I built a policy with two NEW_STREAM directives, one stream with a real file, the other with a dummy file. I ran the policy and got an error 71 on the stream with the dummy file. No surprise there. I then excluded the dummy file using an exclude_list.policy file and ran the backup again. The stream with the dummy file still issued a 71. So - even if you exclude the entire contents of the stream in the exclude file, you still get an error 71 when you attempt it. I, frankly, expected this given how Netbackup implements the exclusion list (it scans for the specified directories files first, then applies the exclusions). I'd suggest what I suggested before, add a single dependable file, like /etc/passwd, to the stream with the raw devices in it so it always has one valid file, the others that are missing won't matter then. You won't even need the exclusion list if those raw devices don't exist on that server. -M -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Paul Keating Sent: Thursday, April 27, 2006 6:23 AM To: veritas-bu@mailman.eng.auburn.edu Subject: [Veritas-bu] RE: [Veritas-bu]Status 71...was: Volume Pools [recommendations please] I don't know why you're getting that error, but it must be specific to the raw backups.

Example Cluster_node_1: / /u /node1 Cluster_node_2: / /u /node2 There's a policy that backs up cluster /data, which is the shared resource, backed up via a virtual name/IP, but I have another policy that backs up the physical nodes. The backup selections list has the following: / /u /node1 /node2 The client list has: Cluster_node_1 Cluster_node_2 There are no exclude lists on either node... /node1 gets backed up on the node1 backup, and /node2 gets backed up on the node2 backup. Never get a 71. Works a charm...so I would venture to guess it's either specific to the raw backup, or it doesn't like that you've specified and exclude list for a fs that doesn't exist.

[Veritas-bu] DSSU/DSU experience

We're considering a few different disk technologies, such as VTL, DataDomain NAS heads, as well as traditional DSU/DSSUs.

RE: [Veritas-bu] DSSU/DSU experience
Steve, Works fine as long as you're at least MP4. Prior to that DSSUs would stage the files in the filesystem sequentially regardless of retention levels. Thus if you're not mixing retention on a tape (but are on the filesystem) you could have the situation where tapes are constantly being mounted and unmounted, killing the advantages of the batch nature of DSSU. With 5.1 MP4 this has been fixed by separating the staging jobs by retention level though you'll want to take note of MAX_STAGING_JOBS and STAGING_JOB_KB_LIMIT parameters. Other note is not to get too cheap of disk for this work, and make sure there's enough of it. One day's worth of problems can back you up trying to stage to tape for several days afterwards.

You can't share DSSU amongst multiples media servers. You can't create DSSU-groups (ie when one is full, switch to another..apparantly fixed in 6.0) DSSU are mapped one-to-one to volume pools, when de-staging. Previous to 5.0MP4, (unsure about 5.1) DSSU's might not purge in time for backups and jobs would fail.

RE: [Veritas-bu] DSSU/DSU experience
DSSU sizing is really important. If the Disk runs out then you start getting status 84's and jobs fail. This seems reasonable except that NBU does not free up the space for the failed jobs until the jobs are restarted. If the job is a large one then you could get several more backup failures from other jobs before the job retries and cleans up the old space from the failed backup. The cleanup process for disk images already copied to tape is not very efficient. I also have had to create a script that checks for disk backup images that are successfully copied to tape so that I can clean up the images to make room for the new backups coming in. The script also checks for high and low watermarks and emails/pages if the disk space gets lower than 90% I also agree that you want to use fast disk for this. We have tested with a few different levels and are now using SAN attached RAID10 I am at NBU 5.1MP4. I am looking at moving to NBU 6.0 MP2 to take advantage of all the new DSSU improvements and features.

[Veritas-bu] can SAN media server restore clients?
can a licensed SAN media server be used to restore data to a client other than itself?
Re: [Veritas-bu] DSSU/DSU experience
Interesting. We have had similar issues with NBU DSSUs. The HPSS (www.hpss-collaboration.org/hpss) seems to be the best option, combined with ACSLS, for our environment. We have HPSS running with other equipment in one of our scientific divisions (www.nersc.gov) and they just rave about its abilities. I note it supports (server,disk and offline storage on the server-side) Solaris and AIX. But the client-side support is there for many, many other platforms, from Cray T3 UNICOS to Linux, where there are a variety of tools to use (such as htar and other HSI unix-like tools). We are thinking about a hybrid NBU/HPSS approach, allowing data to be staged in various areas of storage, based on user-customizable rules. Backups would be on top of the ACSLS and HPSS. Just my $.02. Certainly not the cheapest solution, but it does give more manageability to at least larger SAN environments like ours. hth Cheers! --Chris Ambrose, Monte wrote: DSSU sizing is really important.

Sesar'; 'NetBackup Veritas' Subject: RE: [Veritas-bu] DSSU/DSU experience I have been using DSSU since 5.1 came out. But I have primarily used it for very slow clients so that I didn't block my tapedrives with these backups. It has been working really fine, except the lack of configuration and performance/tuning. And it has been really easy to use. I have upgraded to 6.0 MP2 now, and there are a lot of nice new stuff in 6.0 regarding DSSU, but I haven't had that much time to check it out. But it seems to perform better and there are also more configuration options. Not that I couldn't make a 1 meter list of things I would like to have. DSU's I have only used for testing, so no comments from me on that. But when I looked at it DSSU seemed to me to be a much better solution. At least in our installation. Have never used VTL, so also no comments on that. /johnny -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Steven L.

Re: [Veritas-bu] DSSU/DSU experience
With the recording speeds of todays tape drives, you have to put some kind of disk in front of them, to ensure you have a steady stream of data to record. Without it, your just going to wear out the drives, even faster than before. And no matter how fast tape drives get, they will never match the throughput of disk, and thus never match them, in reducing backup windows. I recently (January) replaced a six drive DLT7000 library with an Overland Storage NEO8000/REO9000 combination. The performance difference is dramatic. And with plenty of disk, in the second D in D2D2T the wear on the tape drives have been drastically reduced. It has taken 4 months to reach the 100 hours milestone of per-drive wear. Something I did on a weekly basis with the DLT7000's. I originally looked at the REO9000 with the intent to use it as a VTL, but (NetBackup) licensing costs, and the virtual media overhead I encountered, in that mode, I chose to simply slice it up onto 1 TB partitions, mount them on my media server (Sun Enterprise 450 running Solaris 8) and use them as Disk Storage Staging Units (DSSU). VTL's do have their strengths. Nearly a unlimited number of virtual drives; and by using smaller virtual media; a high flexibility in the allocation of disk amongst numerous policies. They are nearly the only solution in situations, where the disk staging on the media server is not an option. Many VTL manufacturers are also PTL manufactures, and often tightly couple their offering. Even to the point of staging data from disk to tape, outside the scope of the backup software. DSSU's do have their weaknesses. You are typically stuck with one-to-one ration between DSSU's and policies. This fit my needs, but for those with a multitude of policies to manage, I can see them having problems. Steven L. Sesar wrote: We're in the process of rearchitecting our BUR infrastructure.

[Veritas-bu] Tuning Netbackup
What major changes I'll have to do incase the OS is Linux. The data transfer (throughput) rate is 14mb/sec. cd /usr/openv/netbackup/logs/bptm grep -i "KBytes/sec" log.* transfer rate is 18632.911 Kbytes/sec Let me explain u abt my setup: NBU 5.1 MP3 HP StorageWorks MSL 6000 HP Ultrium LTO 3 cartridges Changes made, but still struggling to get the speed. /usr/openv/netbackup/db/config/SIZE_DATA_BUFFERS = 256kb /usr/openv/netbackup/db/config/NUMBER_DATA_BUFFERS = 16 After creating these files, backup was fired at the speed of 18mb/sec. Do i have to change any directives in /etc/sysctl.conf Cheers, Nouresh
