Mirrors

Our main repo server is located in Germany and contains the pacman databases and packages, matching source packages and installers. The whole content of the mirror is regularly synced to multiple mirrors across the world.

All these servers are registered with pacman under /etc/pacman.d/mirrorlist.*. The first URL in those lists is the primary mirror, all others will be used as a fallback. You can make another mirror the primary one by moving it to the top.

In case you have problems with a particular mirror please let us know by filing an issue: https://github.com/msys2/msys2.github.io/issues

Adding a New Mirror

The repository size is ~725 GiB (see https://mirror.jmu.edu/ for current stats) with the distribution of sizes like this:

  -1K: ~14000 files
-100K:  ~3200 files
  -1M:  ~5000 files
 -10M:  ~4000 files
-100M:  ~1000 files
  -1G:   ~200 files
 -10G:    ~20 files

You can use rsync to update your mirror using

rsync-ssl -rlptH --safe-links --delete-delay --delay-updates \
    rsync://repo.msys2.org/builds/ ./msys2

Our repository layout is compatible with Arch Linux, which means you can use the following script to sync everything more frequently and efficiently:

https://gitlab.archlinux.org/archlinux/infrastructure/-/blob/master/roles/syncrepo/files/syncrepo-template.sh

source_url='rsync://repo.msys2.org/builds/'
lastupdate_url='https://repo.msys2.org/lastupdate'

Since our server has TLS/SSL support, you can replace the rsync command in the script with rsync-ssl.
