How would you backup 500GB?

[beyond-tec]

Looks like we got some tech freaks in here :-)

I'd like to backup 500 GB daily and the backup needs to be carried out of the company (in case of fire)
so I'm looking for a backup solution which can backup 500 GB and ain't that heavy / big.

shouldn't cost more than 1500 EUR.

things that won't work:
- external harddisks
- NAS Stations

so, any ideas how to backup ?


thx in advance

something like this?

750 gig USB drive

French website btw :P

LTO-4 is 800GB/1600GB uncompressed/compressed

BUT... the drives alone run $5k US (not sure how that compares to Euro)

past that the tapes are ~$90 US and you can reuse for some period of time.

Is this for a company or for home? mixed data or all one type (ie all data base)? you may want to look for something in the way of tape backup but a fast google search did not get much. I know there are company's that do it as the company that I work for has everything backed up nightly on them I just don't know he is doing it for them. This Link my have what you are looking for.

How much does the data change on a daily basis?

a differential copy might be your best strategy... do you need it archived in a snapshot? (i.e. able to return all data to a checkpoint in time)

Attix5 is able to do both of these... not sure on providers in Germany but I am sure they must have a representative there.
This is available in both hosted and installed flavours... The smallest licenced protected data is 500Gb. They licence on amount of data to be protected not he space it takes up in the archive system

We were protecting 2Tb, remotely backing up offices all over Europe. For a sales office in Italy we were protecting 200Gb with a daily delta of around 30Gb but transferring < 20Mb over the network (many of the files were PSTs and we used block level differential)

Tape backups FTW.

If you are in the UK, I could recommend a couple of secure off-site Data protectors.

Check out http://www.ironmountain.co.uk

These are the type of people/organisations you should be looking at for off-site data storage.

I don't know about tapes FTW! but if you do go for a tape backup solution (LTO 3 @ 2k€ + 50€ per tape) Compressed you might fit all that data on 2 tapes. if you are taking a daily diff and a weekly full then you are looking at maybe 7 tapes a week (assuming backed up differential data grows linearly) that could be an expensive solution and someone would have to change tapes at 0300! With a decent tape rotation strategy you are looking at 50+ tapes with periodic pairs used only once.

Yup we used to use Iron mountain for Datacentre backups

@clown: looks like a harddisk? don't wanna use harddisks

@elo: 5K doesn't fit in the budget :-)

@gylu: as mentioned in the mainthread it's for a company.
I can't use online backups because we only got 10kb/sec upstream
so a backup of 500 GB would take until next year *g*

@Djarid: lots of datas change. I want a complete backup to aware
that a tape between the initial tape and the last tape is broken.
So I'm going to safe 500 GB each day.

@Wilbur: I love tapes but only found 320GB (compressed) tapes or
the Sony 500GB thingy which costs more than 5K €
Can't upload the data because of the upstream mentioned above


thx for all the replys so far

[Wilbur]

Upload?

They send a nice man in a van to pick the tapes up from you every day :-D

[beyond-tec]

coooool stuff.
he travels each day from the UK to Germany just to pick up our tape?

*ggg*
