Hi Michael,
As discussed we're now mirroring the whole thing so there's no
separate "backup" option any more. A key factor in mirroring
is to minimize traffic to and from the primary server.

Slávek posted the current size:
Current size and occupied space of the partition:
/dev/mapper/lvm1-tde_data 400G 336G 65G 84% /srv/tde
- and there was
some discussion of trying to stay under 600GB over
the next few years.
I posted the bandwidth info:
Primary mirror has 4TB/month bandwidth and has used
876GB about two thirds
of the way thru this month. So about 1.3TB in a quiet month for the
primary mirror. Secondary mirrors will probably see a third of that.
There's more when a release is finalizing - maybe double or triple. So a
2TB/month cap should be OK for a secondary mirror and you might even get by
with 1TB/month.
All other decisions are up to the mirror operator. I did post some
details of the script I use. Other mirrors use different scripts.
I use Debian Buster and Apache2 currently but that may change and
other mirrors may use entirely different software. The CPU and
RAM will of course depend upon the bandwidth which we have discussed
and the software which you choose but in reality it would probably
run fine on a twenty year old Pentium with a gig of RAM.
Please join the TDE devel list if you wish to discuss mirroring further
as that is a more appropriate forum.
Thanks,
--Mike
