In the old days I packed once built toolchains to tarballs and put it
aside and in my backup.  Nowadays I use the pre built debian packages
from http://debian.pengutronix.de/ – maybe that's an option for you,
too?

Although I keep my src archive in a central place covered by backup, I
doubt I have stuff for oselas toolchain 2019.09.x in there.  I can not
remember having used it at all.  Otherwise I could have given you a
copy for your own archive or mirror.
