[Veritas-bu] what license are required to backup VMs as normal client backups
Hi, I have purchased Netbackup Starter Pack with 5 standard client license. I would like to backup some Virtual Machines (win2003, winxp and linux). I have 10 VMs in total. Does each VM have to be licensed if i back it up? Are the client licenses treated the same as physical server backups? I will not be using VCB backups.

[Veritas-bu] NetApp flexClone for backup of Vmware
Hi, I am interested in hearing from anyone using NetApp FlexClone for the purpose of backup of a vmware environment. FlexClone appears to be the product recommended to backup VMs which are stored on a Netapp Volume. In my case the netapp volume is Fibre Channel. I understand how flexclone works but i cannot see how i backup the VMs located on the FC lun without presenting the FlexClone to an ESX server and then importing the VMs. This is a manual process and would not be ideal on a daily basis. The flexclone will be a clone of a Netapp snapshot taken using Snap Manger for VI so that all VMs are in a consistent state.

[Veritas-bu] netbackup VS backup exec - shared SCSI tape library
I am aware that with netbackup I can share a SCSI tape library with a master and media server and that the server that can see the robot can manage the tape mount requests. Is it possible to use backup exec to do this? If i have 2 backup exec servers and one tape library with 2 tape devices - can the backup exec server that can see the robot issue mount requests for the second backup exec server? Or will the second backup exec server consider itself to have access to just one Stand Alone tape device. Am i correct in that the ability of netbackup to do this is what makes it a 3 tier product where backup exec is a 2 tier product and cannot have one server controlling a robot for mount reqeusts for other servers. thanks for any info.

[Veritas-bu] NDMP SSO tape drive backup failing
Hi .Have just configured netbackup 6.5.3 using the device wizard to configure a robot and 2 lto4 tape drives which are Shared on a SAN. The drives are shared between the Linux backup server and 1 Netapp Filers. The device wizard has correctly detected the Robot and 2 Tape Drives which are shared with the NDMP device. I can use the master server to perform a backup successfully. When i try to perofrm a backup of /vol/vol0 using the NDMP storage unit the backup fails. THe NDMP tape devices have not come online under device monitor. I have used the dump command on the netapp filer to succesfully use the tape devices. I have run the sysconfig -t command to see the 2 tape devices. NDMPD status is on. I have used the tpautoconf probe and veirfy and commands successfully to connect to the netapp filer. Netbackup appears to have configured the library correctly with 2 tape devices shared by 2 servers (one linux master server and the other netapp filer). Is there something that i am missing that is preventing these ndmp backusp to work in a shared tape environment? thanks for any help!!

[Veritas-bu] netapp NDMP and snapshot backup question
Hi, I am successfully using NDMP to backup a netapp filer using netbackup 6.5mp3. I have some questions areound the capability of the backups. I can backup the whole volume by specifying the File List of /vol/vol1 (this creates a snapshot on the filer and skips backup of all existing snapshots). I can backup one previosuly created snapshot such as /vol/vol1/.snapshot/hourly.0 ( this performs a point in time backup using the specified existing snpashot) (1) Is it possible to instruct netbackup to backup all snapshots that exist in the ./snapshot folder? (I could not get this to work) (2) Is it possible to use wild cards to backup certain snapshots in the ./snapshot folder (such as ./snapshot/*snap_lun0* The reason I would like to do this is that i am using SnapManager for VI to create my snapshots that exsit on the Filer. Therefore the naming convention changes for every snapshot. I need a way to specify a backup of exsiting snapshots when the snapshot names change for every snapshot - but the names do have a common factor such as 'storage_lun1' or 'every 4 hours' Thanks for any help with this, Mark Send instant messages to your online friends http://uk.messenger.yahoo.com ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
[Veritas-bu] netbackup 6.5mp3 vcb policy failure
Hi, I have created a netbackup flashbackup-windows policy with the objective of backing up virtual machines but i cannot get it to work successfully. I am using windows 2003 netbackup 6.5mp3 and esx 3.02 running VMs of Win2003. I have selected off-host backup and i have selected my VM proxy (also my master server which i have previosuly added as a Virtual Machine Proxy Server is Master Server host properties) . In Policy snapshot client options i have selected snapshot mount point of V:\vcb (this disk and folder exist on the proxy server). All three other parameters are selected as 0 (although i have attempted option 2 with VM backup). I have inserted the client name of the VM and selected All_local Drives. The validation of the advanced client polciy fails with error message of "snapshot could not be created with vmware method". Before creating the policy i have inserted the name of the esx server and username/password under credentials-> VM Servers. I have also installed the VMware VCB v1.5 (downloaded from the vmware website). Before doing this i removed the previous version of vcb which was 1.1 I have permitted the proxy server to see the SAN attached disks which are the VMFS disks on the ESX server and contain the VMs. These disks can be seen in Windows Disk Management. I have successfully used the vcbmounter command from command line; vcbMounter.exe -h -u root -p -a ipaddr: -r v:\vcb_mnt\ -t fullvm I do not know where to look next!

Re: [Veritas-bu] configure nodes of VCS Oracle Rac cluster as mediaservers

Re: [Veritas-bu] Veritas-bu] Data Domain with NBU
Hi mike, i have implemented Data Domain systems on a number of sites using legato and netbackup.The data domain boxes have worked very well at all sites with excellent compression ratios. The support from data domain has been great during configuration and afterwards.The best part about them is that they eliminate tape and library errors and maintenance (apart from the fact that the data is cloned to tape later). The only occasional issues we have had with Data Domain Systems would be: Storage Unit (DD tape device) was unavailable a number of times and backup failed during the backup- resolved by stopping and starting veritas services or rebooting master server. One interesting point to remember is that the backup to DD disk may not be faster than SAN attached tape. You are writing to a NAS file system so there is a performance overhead. On one site we had to convince the customer that a decrease in backup speed was worth it to avoid tape/library errors, tape management and to acheive compression and data replication.

Re: [Veritas-bu] FalconStor vs. Data Domain
I have installed Data Domain at three sites. Two using Veritas Netbackup. ON both Netbackup sites the customers are very happy with the data domain systems. They get great compression ratios and the DD systems have been reliable. The DD support has also been very good during installation and afterwards when required. Both customers are using DD replication for offsite copy of backup data to a DR site. One thing to watch out for is that the backup to DD wont necessarily be faster that to SAN based tape. The backups become more reliable due to absence of tape device/library failures and availability of media. - Try the all-new Yahoo! Mail .
