<b>Subject:</b> [mythtv-users] partial restore of database
from backup<br>

<p dir="ltr">Like many I do daily backup of my mythtv
database. However, I've only<br>
used that backup when building a new setup of hardware
that will<br>
hopefully be doing the same function as the old one, once
the database<br>
is restored and the recordings copied to the right
directories.<br>
</p>
<p dir="ltr">What I'm doing now is different and not sure if
the saved database can<br>
help. I'm build an additional mythtv backend that will be
used to<br>
record some of the same programs but it started with a
clean database.<br>
Both backends are set to record for example "NCIS". My
main backend has<br>
been recording those since the beginning of the series so
when a rerun<br>
comes on it will not record it again because it once
recorded it long<br>
ago, even though it's been watch and deleted.<br>
</p>
<p dir="ltr">The new backend will recorded it because it has
no history. Some of the<br>
reruns are not tagged as such and using that record flag
doesn't solve<br>
the problem.<br>
</p>
<p dir="ltr">So my question is, can I export the record
history of a program or all<br>
programs from one backend to another so the new backend
will not waste<br>
time recording something that's already be seen?<br>
</p>

Any particular reason for choosing two master backends instead
of making the second a slave of the first?<br>

<p>I didn't go into any detail but what I'm doing is playing and
learning with the new backend while I'm home from traveling in my
RV where the new backend will be when we are traveling. We're
usually gone for 4 months and home the rest of the time. When home
it's a good time for computer maintenance and play. So other than
maintenance, the master backend will remain undisturbed. The new
backend removed from the RV is a Raspberry Pi 4B 4GB ram with a
1TB SATA SSD connected to USB3 which is my rootfs and my recording
drive. There I use HDHR Quatro for tuners. I'm sort of parallel
testing worse case scenarios to see how good the RPi 4 is.</p>
<p>If you're interested I documented what I did with the help of
others on the forum: <a
