I've been a Carbonite user for many years. It seemed to work well. I could access files from my tablet, phone or laptop (in addition to my desktop which was the system that was backed up).
Last month, I lost a disk drive. I thought -- no problem, I've got Carbonite. What a mistake!
I tried to restore my critical files (financial stuff for taxes, etc.) using their web interface.
Unfortunately, that interface limits your downloads (number of files and size) too much to get much restored. And, several of the zip files I downloaded were corrupted (7-zip could get some of the files, but Windows couldn't even open the archives).
When I looked at the "Carbonite drive" to do a full restore, it said I had no files saved on the failed drive.
I called. After a long conversation with a tech, I was told there were problems on their end and they'd escalate it.
After about a day or so, I finally spoke to the senior tech. Again, another long phone conversation. No luck. They can't restore my files. Many emails back and forth. Days pass. Finally, they said they'd send a hard drive with my files on them. They eventually did (I had problems getting it since they sent it USPS instead of FEDEX overnight or something reasonable).
To make a long story short, it's two weeks later and I have the drive. It has files from 3 other hard drives on it, but NO FILES from the drive that had failed.
The day before I finally got the drive, I got an unexpected call from another senior tech there. He magically got my files restored online and I'm downloading them as we speak (it will take more than 2 days to get all the files restored).
In the meantime, I see that another drive (about 1TB of stuff on it) shows 0 on Carbonite, even though a month or so ago I was able to access files on it!!! Carbonite said it "didn't look like the drive was selected for backup" -- BULL.
Anyway, I can't recommend them. Website performance is poor. Customer service is inept. Service is unreliable.
