how to create an online offsite storage at home

Hello guys i need help with a small project?

My boss asked me to look into online offsite storage prices, I got him a couple quotes and he was shock at the cost of storage. I explain to him that this facilities have state of the art equipment, software  and that the security they offer is very high end, pretty much as secure as a bank.

He then ask me if i could setup something similar at my home without all the security of course. he just wants to have a backup in case of a fire or flood. he is tired of taking the sdlt tape to the bank.

I want to have an idea of what type of connection would I need at home as well as equipment and if there is software design for this type of project, I'm looking into doing a full weekly backup. about 200GB of data tops.

any help or ideas would be appreciated.

Thanks

Laugh in his face.  Go ahead.  I'm serious.

Well... not really serious.  200GB!??!?!!  That's insane.  How fast is the company's upstream bandwidth?  Assuming T1 (150K/s upstream) it would take the company over two weeks on NON-STOP, FULL BANDWIDTH transfers to upload 200GB to another site - yours or anyone elses.  These offsite data companies also use software that can backup only changed data at the block level, truly minimizing the amount of data uploaded and the time it takes.  

Off site backups are critical... and if you want to do them yourself, you need to look at all the factors.  You could use an external drive and backup the data to that ONCE, take that drive home, then setup an FTP server at home and write a script to backup ONLY changed data from the office.  Depending on what your company does, that may be sufficient.  (How much data changes in a week?)

not a whole lot I pressumed. I would say about 3 to 5 gigs tops.

 I thought the upstream speed of the T1 was over a meg?
Yes, over 1 MEGabit - 1.544 to be more accurate.  But 1 byte = 8 bits.  So 1.544megaBITS per second/8 bits per byte = (roughly) 193 kiloBYTES per second (best case, then you have to allow a certain protocol overhead).  Figure it would take a little less than 2 hours PER GB to remotely backup the changed data.

Got it.

Having broadband at home won't help much right? would it double the transfer time?

T1 in the office and at home is very fast sometimes it reaches up to 2.0MBytes

Thanks for your help and time.
Good luck with it.  I think your better off with a pay service and the software they would use.
