hello,
1. Cache File Settings: By default, the cache file is placed on the volume with the most free space that is not being snapped by the AOFO option backup. If the volume being snapped is the only volume with available space, then the cache file is placed there.
Real time activity of AOFO: When an AOFO option backup is run, Backup Exec creates a Cache File by the name BEVspCacheFile.vsp which is used for holding the "snapped" volume data.
Where to see this File: When an AOFO backup job is running, go to the drive which is pre-defined as the AOFO cache file drive
2.The cache file created by the backup job is always located in the server being snapped by the backup job. The location of the file cannot be specified on a different server.
3. To change the default location of the cahe file to another drive with more disk space on the server being snapped by the backup job follow this technote.
