Backup on different levels, one of my clients who I would say has similar ifrastructure uses following approach:
- backup on the vm level - backing up snapshot of the entire virtualization guest - at least once a week, always before update/upgrade. These can be big - consider ZFS pool w/ compression and deduplication active - but that is also hw intesive. On the other hand, I don’t think you need to keep more than last two successfull backups.
- filesystem level - run rdiff-backup against the / of the filesystem several times a day. SInce it is essentially versioning, you are only backing up new changes. No zetabyte needed here, ext3/4 will do.
- drop database somewhere ideally several times a day - even if there are no incidents, your developers will love you.
The recovery strategy is as follows:
- pull the guest out of the last vm backup
- sync up the files from last rdiff-backup run
- discuss w/ the developer DB recovery - or just recover the last backup and hope for the best…
IMO the main difference between left leaning commedy and the right leaning commedy is that the left can make fun of itself.
Example: The Late Show with Stephen Colbert. Biden catches Covid and his press secretary claims, that “despite his illness, the president is not slowing down”. Colbert finds it believable “because he does not thing it is physically possible to move any slower than Biden already is”. Whole theater is laughing.
Imagine a right leaning commedian said that about Trump. He would get shot!
