Members

Member name Description
PUVFF_SXSBACKUP Side-by-side backup supported.
PUVFF_COPYBACKUP Xcopy style backup supported.
PUVFF_BACKUPSUPPORTED Backup is supported.

All implementations that return either PUVFF_SXSBACKUP or PUVFF_COPYBACKUP should also return PUVFF_BACKUPSUPPORTED. This enables aggregated project systems to AND together capabilities. Visual Studio takes this to mean 'multiple projects support mutually exclusive backup types,' as differentiated from 'no backup options available.'
PUVFF_USE_ALT_BACKUP_LOCATION By default, copy backup occurs in a subfolder of the solution. There are times where this is unwanted. In those cases UpgradeProject_CheckOnly can return PUVFF_USE_ALT_BACKUP_LOCATION. This defaults to using a subfolder under the user's default project location folder. This alternate location should be avoided if it is possible, as it presents more limitations regarding backup file name length.
