Earlier, by change, I found "a way" to recover during
clone/stage on an AFD dev at same time :
The trick is not to restore using client file index
(recoveries browsing files) but recovering using
SSID/Cloneid :
Query the SSID/CloneID of the SS you need to recover.
If the SSID copy has not be staged and purged yet
(in other word, still on AFD), you will get at least
2 different cloneid, one for each copy of the ssid
(one on the write enabled AFD volume,
one for the read-only AFD volume).
eg :
SSID CLONE ID Name Volume
12345678 123456789 c:\ Test
12345678 123456790 c:\ Test.RO
When AFD read-only part is reading (for recover,clone or stage, doesn't
matter),
if you recover using SSID/Cloneid and use Cloneid of the SSID copy from
the Write-enabled volume like
"recover -S 12345678/123456789 [-d <alternate_loc>] path_to_recover"
it will read from write-enabled AFD device while the
read-only one is reading.
I discovered it by chance, when scripting new staging batch
when I did forget to specify ".RO" in <volume>.RO name in
piped mminfo for staging cmd during operators did recover using GUI.
Not using that trick very often but it worked each time in
case of emergency recover.

Come on Stan, let's not be naive about that. EMC had years to fix this
issue and the reason they didn't was that a too good AFTD (maybe even
with dedup, like PureDisk) will compete with their VTLs. Now that they
own Data Domain (and BRS is actually DD), they need to fix it, but I am
pretty sure that you will not see any improvements for AFTD without DD
(that is why DD boost is here).
