Four full months. More details in listing this page[1]

I don't suggest to pay forever, one of the benefits of moving this, is
to stop rely on one guy. We already suffer of a previous shutdown on
this service.

The current server cost is 16.99€/month excl. VAT with 2x1TB HDD with
1Gbit/s connectivity, 200Mbit/s internet bandwidth and unlimited traffic.

A cheap solution based on a dedibox classic[2] with 2x1TB, 1 Gbit/s con,
150Mbit/s internet and unlimited traffic for 29.99€/month excl. VAT.
should be sufficient.

A more future proof solution may based on a dedibox pro[3] with 2x3TB
drives, with 400Mbit/s internet bandwidth and unlimited traffic for
69€/month excl. VAT.

Of course, any Hetzner alternative may fit, but traffic limitation may
cause extra cost that we don't have with online.net offers.

My suggestion would to keep them as far as we can, until costs is not a
showstopper. With a 1TB server and 300GB by year, we can keep ~3 years.

Keeping the git backend or not, it makes sense to me to move this from
the build server (pkgbuild.com) to the archive server (something like
archive.archlinux.org).

Git is an awesome SCM, but it was not think to backup stuff, especially
with a big directory tree. My feeling trying to find a previous version
of a PKGBUILD with aur-mirror.git is:
- a very long time to fetch the repository
- a space based dig into changelog to find the right commit for my date
- a long checkout to get the tree at this commit

Having something with faster access and in a similar hierarchy may have
use cases.

No extra cost is expected for mirroring, which is a kind of distributed
backup. I see at least 2 potentials benefits for mirroring:
- Better latency around the world.
- Get our data back in case of disaster recovery.

Of course, I suggest to keep these mirrors separate from our packages
mirrors. Purpose and HW requirement are not the same.

The only complain I get is because this service is not official and rely
on my health.
I had 3 requests:
- One guy for mirroring because of latency.
- One from ArchARM asking to add ARM to their project :)
- One from a guy asking to add AUR support.
