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.
