Remote Backup

I use a combination of local backups and CrashPlan. My approach overall is to have 3 local copies of everything (including the primary copy). One of these copies is saved on other (older) NAS using rsync. A second is copied back to dedicated internal drives in local desktop PCs using robocopy.

CrashPlan adds disaster protection, and it is much simpler than arranging to store USB drives somewhere else. It is also quite affordable at ~$60 per year.

I thought about hosted servers, but decided not to. The ones I found that had unlimited storage excluded backup in their terms. General cloud services (amazon for instance) turned out to be too expensive when I priced them out. Also, saving the files in an encrypted form would have required time/effort from me to craft the solution. Crashplan was less expensive, and was turnkey.

Dropbox, google drive, etc didn't have the capacity I needed for backup (at least not at the price point I had in mind).

Placing another NAS at a remote location was a possibility, my family generally has lower speed internet service than I have, and it would stress their downlinks. Plus they don't live nearby. Asking friends to host one was possible I guess, but I decided not to ask.

So the main question is why you chose this kind of service over another, which features do you prefer ?

I think I answered most of this. The price point was correct, the functionality was what I was looking for. De-duplication is a nice feature, and it does improve the upload speed of my PC image backups, as well as handling file reorganization (renaming, etc).

Did you look at the confidentiality policy ?

Yes. I also researched their encryption (though most people probably don't have the knowledge to assess that, since it is specialized).

Do you trust the provider with your data or did you make sure that this was encrypted before storing it there ? Have you taken steps to ensure a better confidentiality ?

Crashplan encypts at the client, and claims they cannot recover data without obtaining the user's key. I chose to trust this claim, and I am not adding additional layered encryption of my own.

Are you using multiple providers ?

Local NAS/PC storage under my control, and Crashplan.

Did you encounter any problem (wrong sync, files deleted accidentally...) ?

Not so far (after about two years)

Did you find some limits in the service they offer ?

No.

How do you access the data (frequent remote access, only for backup, sharing with others...) ?

Backup only (which is all CrashPlan does).

Do you value the ability to remotely access your data anywhere ?

Yes, but I use other tools for that.

Do you trust your backup or do you have several others (in addition to your main copy) ?

I answered that above. I don't trust CrashPlan with the only copy, I have multiple copies on multiple devices (including the CrashPlan Central server). In the specific case of cloud, I think this is a business still forming - and that there will be shakeouts coming in the future. So that does create some risk, on top of the normal technical possibilities,

What do you think of the pricing ?

I like the pricing. Overall it is less expensive than setting up and running your own backup NAS.

No.
