(b)  - no
I copied over the original dump log,  with the timestamp in its name.  
I had previously only copied the VTAPing logfile,  with last Thursday’s date in 
its name,
but with the original timestamp buried inside it as part of the data of what it 
was vaulting.
The original dump log didn’t help.  I cannot  re-amvault  it.

However,   hypothesis (a)  seems to be true.   If I specify the timestamp when
I wrote the VTAPE  as my new   src-timestamp,    then I CAN  amvault from the
VTAPE  over to the  LTO5  target tapes.   But I’ll have lost the connection 
with the
original  dump date. 
             Maybe I’ll try it once anyway.   If the original timestamp stays 
INSIDE the logfile,
(I don’t know it it will )  perhaps a restore would still find it,  somehow???

It looks like you can only AMVAULT  once,   not multiple hops.
After I try this exercise,   I’ll go talk to the amanda-hackers list,  to see 
if they already knew
this, and never planned for this to be possible.
