MS SQL VADP Application State Capture (ASC) Backups are Fully Recoverable in NetBackup 10.4
Starting with NetBackup 10.4, VMware VADP Microsoft SQL full backups can be configured for complete application restoration. Before this release, users had just copy-only full backups combined with differential and incremental transaction log backups to restore their MS SQL applications. Copy-only full backups perform ASC, but do not allow for complete application recoveries. Also, copy-only can’t recover the transaction logs on top of those style backups like the new style full backups can. Now users have the option to configure their VMware MS SQL data protection two different ways as shown in the policy and protection plan figures below: The new Microsoft Transact-SQL (T-SQL) full backups configured for full application recoveries. Subsequent differential backup benchmarks are reset so differential backups don’t grow to become the size of fulls The traditional copy-only full backups with incremental and transaction log backups in separate schedules NetBackup 10.4 and onward makes this is possible because MS-SQL full backups are now cataloged as assets in the NetBackup Web UI. Users can now select MS SQL recovery points in the Web UI from either type of backup displayed in the MS SQL assets as shown in the figure below. So, restores work the same way they always have, just with the option of T-SQL full recovery points. Incremental and transaction log backups continue to use the NetBackup client agent. There are a few important notes to consider when using the new fully recoverable MS SQL full backups: This new full backup takes advantage of the T-SQL snapshot feature that begins in MS SQL 2022 but does so in compliance with that snapshot feature’s limitations. Those limitations include that no earlier MS-SQL versions are allowed, or that more than sixty-four (64) databases are included in a snapshot. Microsoft will most likely increase the sixty-four-database limit in the future This new full backup is an “opt in” feature and not the default full. The traditional copy-only full method is offered with the option to use the T-SQL snapshot as an alternative. Neither the “Truncate logs” or “Enable T-SQL snapshots” option are enabled by default Selecting the T-SQL option in a VMware (VADP) policy automatically sets snapshot handling to “Stop the backup if any snapshots exist.” This is a Microsoft requirement to ensure that the database is not in a suspended or inoperable state during the backup All NetBackup servers involved in T-SQL full backups or restores must be at version 10.4 or higher
Virtual Machine Backups Suddenly Got Slow
Hello, In December, our backups of VMWare full virtual machines suddenly slowed way down. At that time a staff admin recreated datastores and bumped the VMFS version from 5 to 6. There were no other changes that I'm aware of. Agent based backups run fine. Only Virtual machine backups run poorly now. It doesn't matter whether I backup to disk or tape, they never achieve a rate above 300 MB/min. Ideas on where the bottleneck is? Something is limiting the communication from Backup Exec to vCenter. I have a case open with support, but they are not figuring it out. I run BE 21.4 on a physical Windows 2016 server. Backup targets are NAS appliances and direct attached SAS tape drives. The server has teamed NIC that connect to three VLAN's: data to servers, second to NAS appliances, and third to underlying SAN appliances that host our VMWare environment. Our VMWare is old: 6.5. Thanks for your help. Ray
Backup Exec 15 Restore from Disk performance issues
Hi, We are having problems with performance when restoring from disk on backup exec 15. We're running an ESXI 5.1 cluster and several servers got hit with ransomeware. We are restoring our fileserver first from a datadomain (Current software 6.0.0.9-544198) target for backup to disk and when restoring it starts at 1468 MB/Minute restore and then drops down to somwehre between 40 and 68 MB per minute. We have over a terabyte to restore in all and cannot afford the extended time to restore. We ensured that the network for restore and connection is set to 9000 MTU and rebooted but still unable to get better speed. Most searches either returns information for restores from tape or backup performance tuning. Until the ransomware, backups were working just fine with no known performance issues.
VMWare restore not restoring nsx security tag
NB 773 Master and media servers VSphere/vcenter 6.5 After performing full restore of vm (vmware/vadp) vmdk the nsx security tag is not associated. The rest of the tags were restored. It was an overwrite full vm restore with same network, etc. Any ideas how to get it to restore the nsx security tag?
Nuts and bolts in NetBackup for VMware: Understanding V-Ray vision through backup process flow
Now that we know how VM discovery job works for a VMware Intelligent Policy (VIP), let us move on to the actual backup job. The process flow described here is the same for both VIP and browse-and-select type policies unless specified otherwise.Harnessing the power of VMware vStorage APIs for Data Protection
Trucks move stuff. The engine burns fuel to generate power. Transmission system sends the power to the wheels. The trailer carrying the payload moves. Trucks consume a finite amount of time and energy to reach destination. We have learned in high school that engines and transmission systems have less than 100% efficiency. You are losing some of the generated power to heat and friction. Let us say you were given four of these big rig systems, all are identical with the exception of the transmission systems. Now you are measuring the time they take and fuel they burn to move a fixed amount of payload from one location to another. You repeat the experiments for different amounts of load. You plot the results to benchmark performance, efficiency and scale. Backup solutions integrating with VMware vStorage APIs for Data Protection (VADP) are similar to the transmission systems in trucks. The engine that really powers the backup process is the set of vStorage APIs. The goal of the backup solution is to harness its power to move data in virtual machines to secondary storage systems. Thus the virtual machines being backed up constitute the payload. As some of you already know, Veritas/Symantec had asked Principled Technologies to benchmark these transmission systems in harnessing the power of VADP. Here are the results. Remember that all trucks are equipped with the same engine (VADP). The load added (from 100 VMs to 1000VMs) for various tests are also the same. In accordance with the strict benchmarking standards, all the trucks were given a few runs to break-in so that the regular day-to-day operating conditions are evaluated. After the break-in runs, three benchmarking runs are conducted for each load. The median value for each truck for each load is plotted above. Let us interpret the results. Performance The first thing that stands out from figure 1 is that the orange truck (NetBackup is represented in Orange. As this benchmarking started before the announcement of Veritas separation we used orange to represent NetBackup) is the fastest no matter how small or large the payloads are. And red truck (Competitor ‘C’) is the slowest! Even at the largest payload of 1000 VMs, NetBackup is 5.8x times faster than the slowest in the herd. The blue (Competitor ‘E’) and green (Competitor ‘V’) are weak when compared with the performance leader, NetBackup. However both are way better than the red truck. The bottom-line: If you are on blue or green trucks and run out of gas, do not hop onto to red truck! It is more like hopping on to an inefficient and slow steam wagon! Efficiency Now let us quickly gloss over figure 2. What you see is the CPU consumption at the data mover. In trucking terms, we are looking at how much gasoline is consumed for the trips and how much is still available in the reservoir if you had wanted to carry more loads. The orange truck (NetBackup) not only completed the trip much quicker but it also did the task with a lot of gasoline to spare. As you see can see we had to specifically draw attention to almost lost orange line in the resource utilization chart because of overwhelming gasoline consumption for pretty much all other trucks. The worst performer once again is the red truck. It is not just slow; it is also a gas-guzzler! There aren’t really any more resources to spare so you couldn’t have added more payload and hoped to finish the trip in the same time frame. The blue truck uses up nearly 85% of resources to for its trip. The green truck starts somewhat well but the consumption shoots up during the final quarter. Scalability What exactly is scale in the context of this benchmark? The scalability is a measure of how well the product performs as the load it needs to handle increases. As you can see from figure 1, as you increase the load NetBackup continues to perform well ahead of the herd. But this data by itself only justifies that NetBackup is #1 in scale. Now let us move to figure 2. NetBackup data mover (media server) is using less than 50% of the gasoline while finishing the task in less than 1/5th of the time when compared to the worst performer. In other words, by the time the red truck moves 1000 VMs, NetBackup could have moved 10,000 VMs! That is 10x better scale! NetBackup is not only #1 in performance but it stays at that position while consuming the least resources thereby making more room for future demands. Thus NetBackup is indeed the king of scale. There is a lot more for us to share with you. How about scalability in recovery? How about storage integration? Will you be at VMworld San Francisco this year? Join George Winter and me at this session to learn more about the benchmark design, methodology, results and lessons learned.
