Some OS's and filesystems have a facility generally known as "snapshots". Using this technique, the snapshot does not change, and is readonly, while the regular filesystem continues. A snapshot does not duplicate things,

it uses the same data unless they change, then the regular file system
uses the new data while the snapshot uses the old.  When the snapshot
is deleted, then the space for the old, changed data is recovered.

However, this have your cake and eat it too scenario is not generally
available and amanda has no builtin mechanism to use it.  Some amanda

users do customize their installations to use snapshots. I hope to with

my Solaris systems as that OS does provide the snapshot facility.

Thank you for pointing me in this direction!
