The SnapInfo directory stores information about each Storage Group set that you create, copies of transaction log files, and other data critical to the backup set. It also contains a SnapInfo subdirectory for every backup you create.
You can change the default name of the SnapInfo directory (SME_SnapInfo), as well as its default location using the Configuration wizard. If you rename the directory (or its Snapshot copies), you must follow strict naming standards.
Specify the location of this directory is when you run the Configuration wizard. By default, the directory name is SME_SnapInfo. However, you can specify a different directory name.
By default, the SnapInfo directory is on the LUN that stores the transaction log files, but this is not a requirement. The SnapInfo directory cannot reside on the same LUN that stores the database files.
The SnapInfo directory name is EXCH__ followed by the Exchange server host name as EXCH__ExchServerName.
For example, you would name the subdirectory for databases that belong to the Exchange server on the Windows host system CLPUBS-WINSRVR3 as EXCH__CLPUBS-WINSRVR3.
For SnapInfo directory backups, Snapshot copy names begin with the string eloginfo__.

Every time a backup set is created, SnapManager creates a new backup set subdirectory under the SnapInfo directory. The contents of this subdirectory are the backed up transaction logs, and the Snapshot copy recovery information.
A complete backup set consists of this SnapInfo subdirectory and the corresponding Snapshot copies of the LUNs that store the databases and transaction logs.
