The problem is Windows itself has identified the volume as a critical volume 
and not recovering it risks operational problems after the BMR recovery.

Hi Michael,

What should also be nice you to give a look is the possibility to 
overwrite/adapt the "critical volumes list". For sample, the use of a directive 
like 

<< 'OSSR_E:\' >>
        +skip: *.*

or

<< '/' >>
        skip: OSSR_E

parsed by savegrp/save to not fork save session could be an easy way to 
decrease DR backup size.

Cheers

Kind regards - Bien cordialement - Vriendelijke groeten,

Understand the challenges.

One thing we are working on in the next release is the ability for file level 
recoveries from DR backups and the ability to perform incremental backups on 
top of those DR backups. This would solve your issues as while E:\ is 
considered a critical volume for DR purposes, the DR backup would support 
standard filesystem recoveries from this backup, avoiding the issue of having 
to backup the user data on E:\ drive twice.

Doubt it. I never set E:\Lotus\Domino as a VSS system file; it must have done 
that when it installed. If so, then moving the data store will simply change 
the entry in the system files (probably).

I could re-install Windows, re-install Domino/Notes to same drive; do a 
standard recovery of the E: drive. Domino doesn't make a whole lot of use out 
of the registry; everything is in their own self-contained files. 
Pretty much the old fashioned way (i.e., the way it used to be with NW 7.5.2), 
and I'd still be able to do my FULL backups and AFTD storage without needing 
multiple TBs of free space. This was never an issue with 7.5.2; it only started 
with 7.6.2. So it's the way the DISASTER_RECOVERY: 
saveset works, since the VSS SYSTEM WRITER never used to save 300+G when I was 
running 7.5.2.
