In my area I've had several people get some variant of encryption ransomware, and I was curious, what backup methoods/services/programs would be reccomended for keeping information safe should this happen?

 

I hear that many of these bugs can also encrypt usb drives and network shares, so I was a bit worried about reccomending hardware backup, but after trying to restore from Norton Online Backup for a customer as well as Carbonite and experiencing how agonizingly slow their services can be, I'm not too sure about online either.

 

Can someone help point me to a back up solution that is secure but also fast enough to be useable?

From Fabian Wosar in his help thread:

Or use a good cloud based solution for your backups that provides strong encryption (so you can be sure that the cloud owner can't look at your data) and provides revisioning (so if you backed up encrypted files without noticing you can go back within the file's history). I use Crashplan for example. Costs me $5 a month. Completely worth it in my book.

A free alternative (for smaller amounts of data) would be to manually backup files to google drive via the web browser interface when you are logged into gmail. If a file is private you would need to place it in an encrypted zip or 7z archive before upload. Files uploaded in this way will be safe from attack unless you have some sort of "sync"ed backup system which automaticvally updates the backups within google drive. You could also make this kind of upload to other email providers which let you store large attachments, or to other online backup and file hosting services, as long as it's a matter of "open browser-->visit site-->log in-->upload files-->log out-->close browser-->clear history,cookies and temp files" then the uploaded files should be safe.

 

Your mention of online backup services being agonizingly slow might be due to poor upload speeds on your connection (if it happens with all sites you try and upload files to), in this case you might think about backing up to cd or dvd discs, some of these are non-rewritable so couln't be edited by malware very easily, but you can't get much data on a cd or dvd disc so you would likely go through them rather fast.

Not everyone resides in areas that offer high speed Internet access and backing up online may not be practical for them. Below are other alternatives for backing up locally.

Disk Imaging & Backup Software:Free alternatives include:Note: If you have Western Digital hard disks, then you can download Acronis True Image WD Edition Software for free.

Don't forget to disconnect your local external drives after performing a backup.

"Don't forget to disconnect your local external drives after performing a backup. " Absolutely! Good advice. It's not a backup when it's still connected to the pc, especially not a backup against malware.

I second that.

Also, consider a file server, such as a FTP server (LAN + fire-walled) with file read permission only, and write disabled.

Any reason you are repeating comments I already made? This is not the first topic you have done it.
