Troubleshooting Exchange snapshot operations

Note the following when you perform Exchange snapshot backup or restore operations:

If you want to restore from a snapshot image, the restore fails if an Exxrestore.env file exists in the transaction log folder for the database. This temporary Exchange file can be left from a previously failed restore. A Windows application event log entry from Exchange tells you that this file is the problem. Remove this file manually before you attempt another restore.
The memory usage of bpfis.exe grows when NetBackup processes a snapshot of multiple databases. In NetBackup testing, the bpfis.exe process memory usage grows by a few MB per storage group or database. If a single snapshot job processes a large number of databases, the process virtual memory size can exceed 1 GB. To work around this issue, make sure that you have sufficient virtual memory to accommodate this growth. Or, break up your backup into smaller snapshots.
