In File backup, DPX backs up data logically file by file. File backup is what you normally think of when you think of backups.
In this backup type, you back up information at the node group, node, disk, directory, or file level. The following list describes each level:
Temporary space is required on the backup source node(s) for File backup. A rule of thumb for approximating the temporary space (in bytes) is 150–200 times the number of files being backed up. The temporary file, created in the directory where DPX was installed, is deleted after the backup.
Files or directories included in the backup definition will not be backed up if they are excluded through a Windows registry entry. The Windows registry excludes some files by default. If you want to back up these files, remove the exclusions in the registry.
To check for exclusions in the Windows registry, run Microsoft Registry Editor (regedit) and drill down to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\BackupRestore\FilesNotToBackup. Remove any undesired exclusions.
Warning! Changes to registries or environmental variables should be done only by qualified administrators. If done incorrectly, such changes can adversely affect applications or operating systems. Contact the Catalogic Software Data Protection Technical Support if you need assistance.
To add exclusions, use DPX rather than the Windows registry.
