The one big difference is that snowflake firms (or any size) tend to lean towards platform-based, agentless backups while DevOps firms almost never take platform-based backups because they have no need to ever restore a full VM, only the data.
MySQL seems to be completely hosed. I'm going to have to rebuild the server, as restoring from backups even a week ago, even at the VM level, is not working!
It's the curse of large companies. Once you get to a certain size you have more than enough unhappy customers (or people with a reason to make you look bad) that will be vocal in any setting that you just always have them no matter what you do. No way to be a huge company without that happening.
I tried adding open-files-limit=4096 in /etc/my.cnf and restart mysql. Then executed automysqlbackup again, this time got something else.
Errors reported during AutoMySQLBackup execution.. Backup failed
Error log below..
-- Warning: Skipping the data of table mysql.event. Specify the --events option explicitly.
mysqldump: Got error: 1142: SELECT,LOCK TABL command denied to user 'root'@'localhost' for table 'cond_instances' when using LOCK TABLES
