internet backup
Greetings,
I'm looking for an offsite backup solution for a company with approx 100 gigs on data growing by about 100 megs a day. They have a 1.5mb T-1 and about 500 gigs of available webspace (through Dreamhost). I would like to have an efficient offsite backup, possibly through nightly transfers of incremental backups. I'm not too keen on keeping continual incrementals as they make restorations lengthy, but rather I'm looking for a way to merge an incremental into an already existing full backup, an effect similar to what _rsync_ on *nix platforms. I've googled around looking for an rsync equivalent and haven't found much of anything.
Is there any software you've used that could fit the problem model I've described? Is this effectively done with ntbackup and ftp scheduling? What do you think?
Thanks.

leew,
Just read through https://www.experts-exchange.com/questions/21817131/Nightly-backup-of-a-win-2k-server-to-a-winxp-pro-machine-off-premisis-over-the-internet.html -- I read a lot of good information, and know your general opinion of these things, though I'd still like to look into making this work. Please let me know if you come across anything else.

Actually, that comment is outdated. I've taken it and turned it into a web page - you might want to read the current version.

I'm also in the process of rewriting it. There are several other things that have come up over the months and seemed appropriate to add. HOPEFULLY, I'll have the rewrite up within a week or so at the same address.
In the meantime, I'll just throw one other thing out there that you may need to consider - legal issues. I'm not sure what country you're in, but in the USA, a new law that went into effect in November or December of last year (just 1-2 months ago) may require you to KEEP all backups indefinitely IF you get involved with legal action - meaning if you sue someone or are sued by someone, you CANNOT destroy old backups from that point until the legal action is completely settled. This can cause your backup costs to rise rapidly and can affect the appropriateness of my previous favorite, disk-based backups. Tape may once again be the most practical solution (much to my dismay).

leew, thank you for the math on time. your article was also a fun read.
rindi, thank you for forcing me to google more and find the first link that kode99 posted, which is kind of what I was looking for.
I'm giving it a shot... I'm waiting the week or so while the data goes, then I'm going to see what it takes daily to make updates. If it fails to work well I'm semi interested in kode99's idea of rsyncing a single file; hopefully the differences won't be too bad.
Thanks again!

In the event of disaster I would consider several options -- Pull the backup from another one of the redundant sources, using this internet option as a very last resort. I could download the data from another faster internet connection, such as a 6mb cable internet connection.
Basically, if I have to use this backup as a last resort, the company has a lot more problems that they need to be taking care of first.
Thanks for the comment
