This is important, and for some media, it should be more often than that.
People forget that flash memory uses electrical charge to store data. It's not durable. If left unpowered for too long, that data will get corrupted. A failure might not even be visible without examining every bit of every file.
Keep backups. Include recovery data (e.g. PAR2). Store them on multiple media. Keep them well-maintained (e.g. give flash drives power). Mind their environment. Copy them to new storage devices before the old ones become obsolete.
It's funny that with all our technology, paper is still the most durable storage medium (under normal conditions) that doesn't cost an arm and a leg.
Sophistication often creates fragility. The human mind marvels at sophistication naturally; appreciation for resilience usually only comes after that fragile thing has broken. Of course it's too late by then.
All them young whipper snappers will continue to learn these life lessons the hard way, it seems.
