freitasm: If you reinstall Crashplan or install on a different PC, providing the data has the same path you can take over ownership of a previous backup and nothing is uploaded.

If you change paths, well...



That is part of the problem. The home server name is the same but the path is different however on the Crashplan site it seems to imply that it will still handle that.

Data De-duplication: This data de-duplication happens at the block level, so even repeated information within a file, as well as across all files, is not backed up unnecessarily.

What I understand about the data deduplication functionality and how it works...

In Crashplan if you take ownership of a previous backup set, and the paths don't match then the files on server are deemed "deleted". If you had the content really duplicated across two different paths before you took over ownership then it would be "delete one path" - "keep other path". Because the content is not "duplicated" since the old path is gone, then it will be "delete" - "upload".

In my case as I was replacing the computer it looks like it comes under adopting a computer..


What happens when I replace one computer with another?
See What happens when I adopt a computer?

What happens when I adopt a computer?
When you adopt computer so that it takes over for another, a number of things take place behind the scenes:
The new computer is assigned the old computer's setting and ID. It ?becomes? the other computer.
The old computer is deactivated. This means that it no longer backs up.
The files you already backed up from the old computer (and now residing on the new computer) are still in the backup archive. CrashPlan recognizes those files in the backup archive and knows not to back them up again.


Of course that is not quite clear if the location is different on the new computer though.

I have done this a couple of times in the last six month (moved from laptop to desktop, then reinstalled OS) and didn't lose anything. Again, the paths were the same all the time.

According to CrashPlan's website, they use 448-bit encryption, and all the encryption is done on the client side. This I like!

Does anyone know what type of encryption, if at all, both SugarSync and BackBlaze use?
The info seems to have eluded me on both of their websites.

Incidentally, it looks like the CrashPlan website is down. Oh dear.

Backblaze use (optional) client side encryption as well... AES(lots) - they call it military grade whatever that means. I'm sure it's sufficient.

CrashPlan --> 2 servers at once, data doesn't move out of my domain, but reporting does and I can get to the data outside of the domain.

It doesn't matter if suitably encrypted data leaves your domain... I would argue that it's more efficient to have a data storage company use their purchasing power, disk space and power for storing what is essentially a useless series of bits without your encryption key.

There are a range of issues here that CrashPlan addresses well.

My points really were:

1. Data in two known locations - many people have countered with comments about FBK operators. 
2. No all of us can afford to move the amount of data that we make.  So being able to push it to two locations at once but within a cost domain can be useful.
3. I can get the data even when it's sitting on machines behind 2 layers of NAT in another location.

The Australians have just spent half a billion dollars pushing fibre past 18,000 homes and just now I read 4 states are without service.

I don't know what Google is worth, but it wasn't so long ago that I was reading they lost 100,000 users email.

Sure, if you want to trust your data (which I read you don't) to a provider to look after then fine, CrashPlan will also do that and you can even license it to use the provider of your choice, so we could even be keeping CrashPlan data within New Zealand.

I was merely driving at the features of the software platform. :)

wow - thanks for all the great feedback.

motivation for keeping it in NZ was that is is governed under our law and would like to support NZ companies.

I have looked at all the offsite ones and see that mozy no longer has unlimited.  great enduser feedback on backblaze and crashplan - thanks.

As Zeon mention, they are a nice bunch of guys and do have some large customers in their enterprise solutions based on a phone call with them today and being in the orcon DC, the ozone is a potential which is attractive to me.  They also do not have any restriction on what can be backed up (exe, etc) or individual file size restrictions.

Hear what you say Timmmay about the small operators, but as this is not their only service and do have corporate solutions, Ihave comfort with them.  

Must admit your solution Freitasm looks great.

Will give iBUS a go and keep you all posted.

How did you get on with iBus?

I see that they are now offering $10 a month unlimited data so looks like a good deal.




Opinions are my own and not the views of my employer.

Hi there,

Thanks CYaBro for the memory jogger.

I signed up for the 2 yr plan which equates to $13/month. I do like the one off payment every 2 years - a sort of set and forget.

I have uploaded about 5Gb of data mainly documents, source code and some music and the only limits have been the speed of my internet connection. I will be adding to this I am sure.

The front end is a very simply to use and runs a single backup set. I am experiementing on how I can use this fully. For example running comodo backup to a NAS say and then iBUS to back up the back up.

The team at iBUS have been very helpful over the phone and also via the helpdesk they run.

All in all a "two thumbs up dave" rating sof far.

Disclaimer: I am not affiliated or related to iBUS, just an end user sharing an experience for others to consider.

I just phoned them as well to see if they would be a feasible option for me if I needed to change. The guy I spoke to sounded knowledgable and was very helpful and honest about their offering.

Unfortunately it turns out their fair use policy would preclude me using the service as their unlimited offering isn't actually unlimited...

http://www.ibus.co.nz/iBUS_Unlimited/Fair_Use_Policy.html

They did point out they have commercial offerings suitable for my level of storage, and in fact highlighted a really nice feature to seed the initial backup with a couriered hard drive (great idea!) but just beware that unlimited is significantly less than unlimited in this case.

(No judgement of the quality of their service here - and in fact I thoroughly appreciate they are being careful to maintain a sustainable business model)

Cheers - N

yeah, had read that thanks. was of the opinion that I would wait and see what happened when I did in fact breach the limits. I am fully aware that this plan is for the home user and not a commercial grade one.

I am thinking that I would top out at say 50-80G at a best guess....

thanks for the heads up on the commercial offerings - they do sound interesting.

I use www.1tpan.com. Its free, 20GB, supporting Windows, Android, Iphone and Ipad. Its owned by a big Chinese software company - Kingsoft. Its reliable, fast and has a forum to support the users. You can register with different email addresses, it means you can get unlimited storage space.  And it has a "multi-channel backup, high-strength encryption" feature, cooool isn't it? But sorry, it only has a Chinese version, no english. But it would be a blessing for those who can read Chinese or can read icons.

Another one from same company: Kingsoft KuaiPan is also supporting Windows, Android, iPad and iPhone with free 5G storage space (could be upgraded to 15G later). KuaiPan can automatically sync your files between difference devices or platforms.    

2GB free? I feel sorry for you guys..   Undecided
