For pictures I think Flickr is ok. For the rest, go with the others.

You shouldn't be counting on an online site to hold your only copies of anything. Even with my online backup service, I make sure to have a local backup just in case something happens.

Ultimately, anything that's free can go away with little or no notice. And even sites that you pay for might well go bankrupt in a short period of time. I remember a law firm in a building I used to work at went from profitable, prestigeous firm to out of business over night during the height of the credit freeze when somebody called their debt and they lacked the cash on hand to pay it.

doesn't apply here, these firms are usually bought by bigger firms like Oracle bought Sun Microsystems,
if one day yahoo has problems we will know that - they will sell, or if google has problems will know
law firms don't have anything interesting to sell

When it comes to valuable data, make backups of your backups and backups of your backups of your backups... You get the idea. Don't get all cheap with things that you care about. Any company can go bankrupt, experience massive hard drive failures. If something happens to you for a few months or years and you forget to take care of your accounts, they can be deleted for dormancy.

You're obviously not American. Law firms in the US are one of the most reliable enterprises you can get into. There's always a steady stream of individuals in need of services.

Whereas, tech companies buy and cancel products in short periods of time and leave users high and dry if they're not paying attention. Just look at what happened to Geocities, people thought that sore would be there forever.
Which reminds me, Google didn't back data up early on, and eventually some folks using Gmail ended up losing most of what they had in their email account because they hadn't taken responsibility to back it up themselves.

yeah you have law firms and banks that are very reliable

It's sorta like hostile espionage though, spying on a foreign citizen private info without any authority.

Banks have nothing to do with this. And you're Romanian, precisely what do you know about the US legal system? Law firms are some of our more reliable businesses.

He didn't say trustworthy he said reliable. Most of our banks our unreliable, but most law firms stay in business for quite a long time.
The only thing I have noticed in some of the firms that may be considered unreliable is that they seem to go through partners like crazy.
You will have commercials for Damien, Voorhees, and kreuger. And then in a few years, Damien Voorhees, and Myers with a new law firm Kreuger, Lecter, and Chucky. Then in a few years, they will get rid of Myers and Kreuger will come back to the original firm. But otherwise pretty reliable.
