- You left out the ACCOUNTNG.DAT files. These are never backed up to
- incremental backups because they are typically opened at boot time and never
- closed. Since they are continuously open, you can't do the usual stuff with
- the file header (anything with "SET FILE", "SET PROT", etc.) but you can mark
- them as modified by renaming them to themselves. Give this a try. It is
- directly from the incremental backup command procedure I use:
-
- $ set proc /priv=(sysprv,bypass)
- $ rename /log sys$sysdevice:[sys*.sysmgr]accountng.dat; *.*;*
- $ if f$search("sys$system:jbcsysque.dat") .nes. "" then -
- rename /log sys$system:jbcsysque.dat;* *.*;*
- $
- $ backup /ignore=interlock ...
