The host crashed due to T434532: reimage it, put it back into production and reprovision its data for extra redundancy of database backups. CC @Marostegui just for awareness, nothing required from you atm.

db2201 has been added back in the backups rotation for s5.
Once confirmed backups work fine, I have to remove s5 from db2250 to leave that config on how it originally was before this: https://gerrit.wikimedia.org/r/c/operations/puppet/+/1324577
This has worked fine - I will work for the s5 dump to be also done correctly before proceeding with the removal in db2250 (dumps happen on Tuesdays):
