Dear users of stat1004,
as it turns out, the backup of /srv will take a total of about eight hours or so. Thus, we will only do the backup step today (UTC/CEST), and the reimaging first thing tomorrow.
Apologies for this taking longer than expected. I'll send an update here as things progress.
Best, Tobias

Dear users of stat100{4,6,7},
we are planning on upgrading stat1004 to Debian Buster this Thursday (2020-09-17) after 12:00 CEST (10:00 UTC). We will reinstall the machine, preserving user data (home directories, /srv), but to be on the safe side, we will backup that data. After the reinstall and a few tests, we will send an all-clear to this list.
A few things of note:
- It would be greatly appreciated if you cleaned out unneeded data before
the backup time mentioned above, thus speeding up backup (and restore if we need it).
- Any changes made to the file system contents after the time mentioned
above may be lost.
- Around the time of the backup, both cron and systemd timers will be disabled, and still-running process may be ungracefully terminated.
If this process works well, the remaining stat100x machines in need of update (6, 7) will be processed in a similar manner.
As always, if there are questions, do not hesitate to contact us.
Best, Tobias
