10 things that block your Happiness
- Self-hatred
- Not being able to let go of the past.
- Not being able to forgive yourself.
- Not being able to value who you are.
- Assuming RAID is backup.
- Not making backups.
- Not verifying backups and finding out restore time.
- Needing other people to validate you.
- Letting other people define who you are.
- Trying to be perfect and to please everyone.
RAID 0 is the best way to ensure data redundancy. It’s what we use at every Fortune500 company and there’s not an issue.
I prefer RAID -1, which is like RAID 0 except that you routinely yank one of the drives so that only the fittest of the bits survive, greatly improving the quality of your data!
Evolution in practice!
I can validate this. I work as the IT ops guy for every Fortune 500 company and we only use RAID-0 for backups.
A singular raid0 for all of them to make sure it’s safe
what? 🤨
You made me doubt a second
Pro tip: Copying a Postgres database while live transactions are interacting with it frequently results in a corrupt backup.
Thankfully I test my Luanti backups.
Edit: I should clarify - My dangerous backup method was a naive file copy. I’m sure there’s a different correct way to do a live backup. I just haven’t checked into it yet, since stopping my Luanti server for a backup is no big deal.
Seriously? Dammit
RAID with parity is technically a backup, just a mostly ineffective one. It’s a backup that allows you to recover from exactly one scenario, single (or double) device hardware failure.
But I definitely understand the mantra “RAID is not a backup”. It’s not what most people think of when they say “backup”.
- Social media
IT team is in charge of backups. They swore up and down that everything was fine and backups are working correctly.
For my department because I believe in Happiness, asked them to send me a backup. It was garbage data.
Then I learned how they verified the backups were working if the file size was bigger than 0kb.
I recently changed my hosting provider and wanted to install the new server from the backups I’ve been creating daily for the last four years. Well, it turned out the backup process got stuck on a lock file in July, 2021. And the email process that should have notified me was broken too. I was so happy I didn’t find this out in an emergency and spent more time testing the email notification this time.
If only my happiness supported non-blocking I/O
Don’t forget being forced into the office
