Migrating Placeholders from old lun to new lun

This issue has been solved. See solution.

Hello,

I have a Windows file server that has a large number of files (50TB, many millions of files) archived with Enterprise Vault.  Time has come to replace the SAN storage unit attached to the server so I would like to migrate the archived stubs "placeholders" from the LUN on the old SAN to a new LUN on the new SAN.  I know that Enterprise Vault FSA has a placeholder migration tool in FSAutility, I tried this and found it to be very slow, I estimated it would take around 3 months to migrate the placeholders using this.

Is there a quicker way to do this?  Is there a utility like Robocopy that I can use to copy the placeholders without recalling them? (I tried Robocopy and it doesn't work).  From what I understand, I need a utility that will copy the "placeholders" (reparse points) as "placeholders" and that will also copy the alternate data stream that goes with them.

Many thanks

Richard.

I always used FSAUtility to move the PH to another storage. I think there no other utility to move them.

I am afraid I have to agree. Since the placeholders are customised by Symantec, only they know how to deal with them.

There is a pretty comprehensive white paper which discusses the options and processes, called

Migrating and Consolidating File Servers with Enterprise Vault

Which you can find here

If you want to dig under the hood nirsoft have a handy utility called Alternate StreamsView which allows you to investigate alternate data streams

Hope that helps

Dear all,

Many thanks for your help.  I think I've found a way to move them using NetBackup - this appears to understand placeholders so backing them up and restoring them should work.

Many thanks.
