Deadlock & environment cleanupWine retailer, anonymized × red9CS-0624
Cut deadlocks 77% on a busy server and automated a manual staging refresh
The findings. A wine retailer running a paired staging and production estate had a few things working against it. One busy server was throwing 26 deadlocks a reporting period, the production-to-staging refresh was a manual chore someone had to babysit, the replication setup had config problems, and backups were sitting on storage that cost more than the job needed.
What we did. We put about 26 and a half hours into the estate: tuned the staging server, rewrote the production-to-staging refresh so it runs itself, sorted out the replication configuration, and moved the backups onto a cheaper disk tier. Deadlock counts were tracked before and after on the busy server.

Deadlocks
busy server, per period
How the figures break down. The 77% is 26 deadlocks a reporting period against 6 after the tuning, measured on the same busy server. The rest of the work, the automated refresh and the replication and backup fixes, comes straight from the engagement log for those 26 and a half hours.
The result. Deadlocks on the busy server dropped by more than three quarters, the staging refresh runs on its own instead of eating someone's afternoon, replication behaves, and the backups cost less to keep. The estate takes far less hand-holding week to week.
The technical detail
What the work covered. The busy staging server was deadlocking under its reporting load, the production-to-staging refresh was manual and error-prone, replication carried configuration faults, and backups were parked on a storage tier priced above what the job required.
What we changed (identifiers generalized for privacy): we tuned the queries and indexing that were colliding to bring deadlocks from 26 a period down to 6, scripted and scheduled the production-to-staging refresh so it runs unattended, corrected the replication configuration, and retiered the backup storage to cut its cost.
