    Hi, Anyone know how to restore data from tape to a different disk or storage device?

    For example, the Exchange Database backup on tape successful on last week, and now I want to restore and check data, but not the original data disk.

    Can I restore it to another spare sever and test?

    Yes it is possible to do this.

    To assist more it would be helpful to know the version of exchange and if you used VSS or not.

    If vss was used you can use the restore options in the white box on the bottom of the restore dialog the pops up after the "recover all selected" button os selected.
    For non vss backups for exchange you can go to advanced and use the options here for non vss backups.

    To restore to a different exchange into exchange you will need and exchange agent on the destination server or a restore only agent of you are using 9.0.
    If this is not possible you can use the out of place options above to a non exchange location and specify a UNC path for the destination.

    Hope this helps.

    Thanks Patrick,

    I made a mapping drive on the exchange server, and try to restore on it as the new destination.

    but a new error occured:

    Event Code: 27:111

    Description: The Exchange Server returned the following error message: [0xc7fe1f41] - [Unknown]. Please make sure that the databases you are trying to restore are not mounted. API: [HrESERestoreAddDatabase()], Item: [Public Folder Database]

    shahai,

    Have these backups been done with or without VSS? Depending on that will decide what your restore options are.

    Restore to Network Drive/NFS-Mounted File System

    Besides restoring/recovering/retrieving data to a client computer’s local drive, you can also restore/recover/retrieve data to a UNC path (Windows) or NFS-mounted file system (Unix). This is similar to a cross-computer restore/recovery except that:

    * The restored/recovered data passes through the client computer to the mapped share/file system.

    * The computer that hosts the share or mounted file system need not be another client within the CommCell.

    All data restored/recovered/retrieved to the shared directory assumes the security attributes (i.e., permissions) of the parent directory.

    On Windows computers, UNC path of a shared drive can be specified. (e.g., \\servername\sharename). (A drive letter associated with a mapped drive cannot be specified.) The Windows logon information for this shared drive must be added in the Advanced Restore options dialog box.

    On Unix computers, clients with NFS mounted to another machine can restore to that mount. (Click the Browse button to see if the mount is visible.). UNC paths are not supported in Unix.

    Hi Jweir

    I'm trying that out right now but I'm having issues with UNC path and I don't see anywhere to input logon info for this shared drive.

    I'm trying an exch2007 db out of place restore to UNC path.

    Error I'm getting:

    The restore should run as the user that is specified on the properties of the exchange database agent in the gui. I have also see where customers have made changes to the network service account in dcom config (posts on this forum). Can you open the share up for a test? Another helpful log is the extidbbackup on the destination exchange server.

    Hi Patrick

    Thanks for the reply but the user defined in the exch agent has full rights to the share I'm restoring to.

    It's a CIFs share on our storage it's not another exch server, will that work?

    I'm accessing the share using UNC

    Restoring to a local drive on the exchange server worked fine but I don't have enough space on the exch server that's why I'm using a CIFS.
