We have one VM having HP-UX, on which a storage area is already mounted from SAN as block level vxfs. We need to share the same storage area on another VM in real-time read-only mode but we can only use Linux or Windows for this one.
Can we do that? If yes, How?
I have RAW LVM volumes I've exported as a snapshot from a Falconstor/EMC Symmetrix virtual SAN appliance. Upon these logical volumes are Xen virtual guest servers which are present to a backup server (Linux box with netbackup client) when we mask the SAN snapshot (timemark) LUNs to the media server.
I'd like to send these guest images (which are within a LVM logical volume) from a SAN snapshot off to Netbackup for tape archival, without converting the guest image to a file on a filesystem readable by a netbackup client .
Whats the best way I can send the raw data from a physical volume (SAN lun) to Netbackup ? I know its possible as the Oracle RMAN tool does this for Oracle ASM disks.. I'd like to do this with a linux native tool.
Thanks MUCH!
I'm going to use a block-level backup solution to backup a Hyper-V server running SBS 2008 plus two additional instances of Windows 2008. It's fairly lightweight in terms of relative use. Total file sharing size is only around 100GB. Size of Exchange is 50GB. I'm thinking that the total size of all backed up volumes will be in the neighborhood of 300GB.
I'm not sure how I would collect data on the existing system to estimate this. Storage growth is fairly low; less than 20GB over the past year which includes file storage and Exchange.
What I'm trying to do is estimate how much backup history I can get on 1TB media, backing up in full once every 24 hours, 7 days a week. Again, this is block level backup, not file level. Thus I'm trying to figure out how many blocks might change per day.
While I know there is no clear-cut answer to this, would 1% be too low? Would 10% be too high? Which continent is my ballpark on? Thanks.
I've always been a block level kinda guy but I'm interested in hearing some real world experiences with file level cloning. What are some of the advantages and disadvantages as well as what tools work the best.
