--verify-at-time xyz
Wondering about --verify-at-time xyz
What exactly does this switch do?
From my understanding of the man-page, it appears to "recreate" the
actual file based on the date used in xyz, and then compare a *new*
computation of the SHA1 hash with the SHA1 hash calculated and
stored when the file was placed in the repository on date xyz.
i.e.
new sha-1 calc
-(from taking the current file, and applying all applicable
-rdiffs, then recalculating the sha-1 hash)
vs.
the stored sha-1 calc when the xyz backup was done.

Is that correct?
