I agree with icefreezer. They lost every appeal with the new plan. And they does NOT provide a "auto renewal" stop option. So i decided to use it until the very last week and then stop the subscription al together.

They are no longer a good solution for people looking to backup large amounts of data on a single computer.

They changed their plan from $5 a month for unlimited backup storage to:

50 GB for $5.99 per month (includes backup for 1 computer)
125 GB for $9.99 per month (includes backup for up to 3 computers)

You may add additional computers (up to 5 in total) or 20 GB increments of storage to either of the plans, each for a monthly cost of $2.00.

Bad UI and very slow compared to other solutions like SpiderOak.

Mozy is not an alternative to DropBox but perhaps useful to keep this reference to Mozy here for those people who may be uncertain of the differences.

For the record, I use Dropbox and Mozy for the purposes they were each intended.

DropBox requires proactive intent to make a file or folder available across the sync'd computers and on the web site. As soon as a change is detected in the contents of the Dropbox folder, the sync is started. On a LAN this sync'ing is almost instantaneous. One excellent use for for DropBox is in gathering together screenshots from multiple computers, using a tool like Jing or Snagit, e.g. for inclusion in a document or blog post. Dropbox makes this so easy.

Another big difference is that a single Dropbox account allows sync'ing across multiple computers (that's the whole point, after all), whereas Mozy is one license per computer.

Mozy is not intended for frequent access to the backed-up files. It is primarily a system recovery tool. Recovering files is no where near as convenient as with DropBox, but that is OK as it's not something you expect to do often.

I've used it for over 2 years now and am pleased enough with it as an off-site backup solution to renew each year.

I think some people could consider it an alternative to DropBox because you can access your backed up files via the web. But unlike DropBox, it's not primarily designed for automatically sharing files between desktop computers. So retrieving a file via the browser takes a few steps. But the fact that all your important files are backed up to MozyHome is great; you don't have to remember to put a file you might want in the DropBox folder.

Used it for a year, ended up not liking it. Not comparable to Dropbox or other sync solutions. It's backup only, runs on a periodic backup schedule, rather than backing up continuously, the UI for selecting which files to back up is highly confusing, and the client app is clunky, runs very slowly, and consumes a lot of system resources.

The whole service / app just seems outdated and limited.

I used Mozy for a while but had some small issues with it. Don't really remember what but i use Jungle Disk now which im happy with.

I've been using it for years now. Set & forget, 100% safe. Great app!
