Re: Ndmp backup restored on Windows System

Jump to solution

thank you but the network bandwith between two sites is only 20 mbps... 6 TB of data are impossibile to keep it online (even with celerra replication)...

Our DR site is in housing with a Service provider... for this year is HP but probably next year could be IBM (it's business... you know...)

Does exist any way to emulate NDMP host on windows or linux?

I've spent all of Company money in this storage... I cannot ask for more in order to buy a new storage (plus you've to consider that my DR provider ask for money also for hosting my server/storage)

i understand your concerns, but it is what it is, enterprise solutions cost money. How about a home grown solution where you use robocopy or something of that nature to copy data from Celerra to remote Windows server.  Initial Robocopy will be a full copy (you can do it onsite before you ship the server to DR site) but after that robocopy will be sending just the changes. Windows 2003/2008 has built-in shadow copy functionality so you could use that to create some sort of revisions. Get a cheap sas/iscsi array and attach it to a windows server at DR site and use it as your target.

20mbps isnt that bad - we got customers doing Celerra Replicator over less

since the replication is only transferring the changes what really matters is the change rate - not the 6TB total

there are NDMP servers - like for OpenSolaris - but that alone doesnt help you

the NDMP standard does only regulate the control flow but NOT the format of the actual backup data

for that every vendor implementing NDMP uses his own format (for a good reason)

the backup software like Veritas Netbackup doesnt understand these specific formats - it just treats it like a database server storing a BLOB

so in order to restore a NDMP backup on a different platform you would need a piece of software that understands the Celerra backup format

in the post that Peter pointed to its described that CommVault did write such a software for Windows - other backup vendors are free to do so as well

Second Question: Our File Server backup now consists in 6TB of data volume and 4,5 millions of files, so we'd like to implement Ndmp in the future (on Celerra) in order to reduce backup time.

Can I restore my NDMP backup on a Windows system? On our DR site we don't have any ndmp appliance (only a DataDomain VTL) and we've already tried to restore on a Celerra Virtual Machine but it's very very slow....

Any suggestion will be appreciated...

or dont use NDMP - use regular LAN based backup - that can be be restored by any Netbackup server

Thank you.

Probably it's the only thing that I can do. I'll lose speed backup benefit... But I'll improve compatibility...

Another Question: Our DR plan involves 100 users (instead of 800 like in production enviroment)... Do you think that Celerra Simulator can host 100 users profile (windows roaming profiles) that could be logon all togheter in the same time? (easily, can Celerra Simulator manage randomic access of 100 users?)

Second Question: Do you know how can I restore windows share in my dr site? Nowaday I can do it backing up my lanmanserver registry (on windows machine)...

How can I do with Celerra in order to easily restore on windows server?

Thank you for your help!

There is a utility called sharedup, which copies the share informations between servers.

no - thats not what the simulator was built for
