Hello, I have setup an sftp server with some help in this same forum.

I want to back it all up to the internet now. I've seen crashplan and backblaze and they seem pretty cheap. My main concern is that I want to be able to do an incremental backup and be able to go into the backup program and recover files by date. So for example, does any service offer me being able to recover files by picking a date and getting all the files as they were that day?

Something like the program Back In Time, but for online.

-Thanks

Also, what about using amazon glacier. Is there anything that can do this with their service?

What dont you yse rsync and configure it out as you want. You can create backup everyday and updates files you need and so on...

Rsync seems to have some basic design flaws. In my experience it has trouble with special characters in the file names and it also has big problems when there are long file names. I've seen tons of linux gurus swear by it, but I just can't get how they can use it in a production environment when it has such basic flaws that have gone unfixed for years.

That point aside, I'm looking for something that is going to be offsite. If the server and computer gear in the office is ever stolen, I need to have a backup somewhere. That's why I asked about crashplan, etc.

Any ideas? What do linux admins use for offsite backups?

Yeah, rsync, basic design flaws and all.

But how can rsync be trusted when you can't predict that someone is going to create a very import document or folder with a long file name?

You can't. move on.

If it can't be trusted, why do people use it? I can't be the first to ask this question. Surely someone has a good reason.

Which is the lmitation?
Tee limitation is about 260 chars as I know.[COLOR="Silver"]

The problem happens if you have a directory that is 200 characters, then you have a sub directory that is 200 characters, and you keep that going about 10 times and then have a file that is 200 characters.

I don't know the exact limit, but I have run into this issue several times. People love to save web pages from the browser and those pages have huge file names and directories. That's just one example of how this happens.

Tar before sync may soñlve that problem. Sync support that option.
