Mozy Logo
A while back we had the opportunity to test Mozy, and since then the platform has only gotten better. Initially we liked the entire concept, but wished for a few tweaks here and there. Apparently Mozy heard our requests, took them to heart, and has continually improved their service accordingly. It is rare when a company takes reviews to heart so quickly and without at least a minor amount of resentment, but all we can say is that we are completely impressed with Mozy. Our review of Mozy has been updated to reflect the latest developments, but the bottom line is that it is difficult to find a company as eager to adapt to market and customer needs.
Where will Mozy be in a year? Nobody knows, but certainly the company’s dedication to improvement has not changed. If there is any weak link in the entire online backup arena, it would be that broadband performance is still not increasing as quickly as hard drive storage capacity continues to grow. Hopefully, fiber optics will solve this problem in the near future. When that happens, Mozy might be a standard feature on all new computers.

Really, I’ve been running it for awhile and have not had any problems. Thanks for the heads up if I start running slow, but I really like it. What back-up program did you go to then?
I haven’t replaced it yet. I’m considering Carbonite but for now I’m just making manual backups.
Very informative post. By the way, how do you tweak Windows Task Manager to show I/O read and writes?
I should have STFI first. =p
Ctrl+Alt+Del > Task Manager

I’ve discovered the same thing about Mozy. It took me forever to figure out which program was causing my computer to crawl. I’m looking into other options now. I’ll miss the Mozy price, but I’ve lost a lot more money in productivity.
I’ve been using Mozy for about 6 months and I now officially HATE it. I had to do a PC Restore on my machine due to some windows problems, so I figured I would be fine because all my files are backed up on Mozy. So I’m done with the restore (to factory settings) and I’m ready to get my files from Mozy. Only when I go to their website to do a Web Restore, I get this error message EVERY SINGLE TIME:
—————————————–
There was an error while restoring.
There was an error processing your restore request. Please try again later.
Try to restore again
—————————————–
I’ve been trying for hours now. And this isn’t the first time this happened to me. A couple of months ago I tried to restore and I had the same problem. I eventually gave up and got the files off of my wife’s computer, where I had still had them backed up from before using Mozy.
So yeah, their service seems great when you first start using it. Nice little program, runs automatically, etc. But if you need to actually restore your files, WATCH OUT. It might take a LONG time. Oh yeah, and they don’t have live tech support either. You have to e-mail and then wait…………probably until the next business day. I’m definitely canceling my subscription after I get my data back. I’ll try somewhere else next time, or back up to an external drive and keep it offsite.
I’ve been using MozyPro with no problem at all.
Mozy will be doing lots of reads and writes when performing a backup. Was Mozy performing a backup, when all this was going on?
I set mine to run at 2AM. But clearly, if you are trying to work on the computer, and do a backup at the same time, you will get performance problems.
I agree. Mozy KILLS your performance.
I wanted to use Mozy to backup my software that I write for my work (in a subversion repository). I also build my software on the same system. Normally I can build it in about 5 minutes, with Mozy the whole things times out after 35 minutes!
After removing it was back to normal. Then I tried again, set the schedule to be at midnight but even without any backups running the build time went up again.
Basically, Mozy can work if you do not have any processes running that perform a lot of disk access, if you do, you better forget about Mozy.
same problem… after establishing a backup every time i opened a folder of even 15 image files windows came to a grinding halt. for as long as 20-30 seconds. their tech people said it was my antivirus and firewall. wrong. as soon as i uninstalled everything sped back up again.
i’m now fighting them for a refund. ugh.
Of course your system will be slow when Mozy is backing up, why is this a surprise? It’s sucking files off of your system as fast as your internet connection will let it. Also, Mozy tech support is correct about your A/V making it worse. Modern A/V solutions scan in real time reads and writes to the disk. Since Mozy is cranking your disk, your A/V is going crazy trying to scan every byte getting read. Re-install Mozy and disable real-time scanning (or setup folder exclusions for the folders you are backing up). Also, set it it run in the middle of the night. Still, I have Mozy cranking out 2 m/bs on a dual core machine right now with 4gb of RAM and I can’t even tell it’s running.
I’ve seen the performance reduction issues running on a P4 with 1 GB ram. The issue seemed to get worse the more I had backed up. (or maybe it was the more I had SELECTED to back up) Anyway, I have over 300 GB backed up (took five months) and the performance of the machine is acceptable after making some changes to the client settings.
I have the following two settings checked (on the options tab) which improved my performance:
1. Disable icon overlays in Windows Explorer.
2. Don’t show virtual drive in My Computer.
Also, since I have so many files backed up, the configuration screen takes a long time to open up. I don’t think there is a fix for this since it has to read a lot of data.
My PC is now dead and I am building a replacement. The motherboard and one of the hard drives are fried. I got most of my data back from Mozy with the exception of a few large (18GB) video files which are taking days to download. (I have them on the original mini dv tape anyway) Without Mozy, I would have lost about six months worth of non-replaceable personal photos.
I will be installing Mozy on the new machine and contacting them to sync up the files from the old backup to the new PC. I’ve read it can be done. If not, I’ll consider a new backup strategy.
I’ve done as Herman suggested and it’s restored the speed of my system to normal. I think the problem has been Mozy searching to see if any icons needed updating in the folder.
I have experienced the Mozy slowness first hand. Like the other post, it took me forever to figure out that Mozy was the culprit. My PC was extremely slow and couldn’t figure out why. I keep a detailed Change Control Log of my PC, maybe because I’m an admin. The funny thing was that Mozy worked fine off the bat, it didn’t slow the system until several weeks later, so I didn’t think it was Mozy at first. The I/O Reads and Writes gave it away. As soon as I uninstalled Mozy, performance returned. And yes, I tried everything prior to uninstalling Mozy, Firewall, A/V, schedule at 1am, blah, blah. I am now happily running CrashPlan without any performance issues.
Wish Mozy could have figured out my issue as I WAS HAPPY:(
Jeff,
re>Of course your system will be slow when Mozy is backing up, why is this a surprise?
Because it doesn’t have to be that way. Backup should “get out of the way” when you need your system. CrashPlan has several technologies that do this.
CrashPlan can be configured to use 0-100% of your resources (disk I/O & CPU) when you’re using your computer, and 0-100% when you walk away. You can control how much bandwidth you’re giving your backup. You can use QOS flags on TCP packets so it doesn’t interfere with your VOIP traffic.. there are a few examples.
Best of all, with your own destinations, CrashPlan is free.
We also have much better compression than any other online backup product out there.

I’m thinking about getting Mozy and I’m curious: what types of connections do the commenters have? I’m getting Verizon FIOS next week and would like to know how well it will work.
If you are looking for an alternative to Mozy, Carbonite, you can check out our data protection service online at http://www.tomnica.com. Not only does it provide a great backup service, but it also allows you to wipe or encrypt data in case your device gets lost or stolen. Finally, you can monitor your device by using features such as screenshots, webcam image capture and device location tracking. All these services are available in 1 package with a neat web interface. We have a free plan for 1 year. Try it out and let us know what you think.

I have been running Mozy for about 6 months and have gradually seen my laptop performance degrade. It took me a while to find the reason since I did not initially suspect Mozy. I have my system configured to backup once per week (on Sunday – it is now Wednesday). In fact, if I look at the configuration window, I actually have backups temporarily disabled.
However, I am currently running a process monitor, and Mozy is the MOST ACTIVE process on my machine and appears to be running through every file in the backup set. Why is this process even active? I have no backup scheduled for another 4 days.
I agree with previous posters that some degradation in performance is to be expected WHEN A BACKUP IS BEING RUN. However, this program is killing my disk right now and no backup is supposed to be run.
About to uninstall.

My computer got really slow whenever I opened explorer a couple of times. With Task Manager, Resource Monitor and Process Monitor I tried to figure out what is going on. Basically explorer used more and more memory the more it was used and didn’t release the memory after closing. Initially it used around 200mb (already a lot!) but after opening the first explorer window it used >500mb, then after closing and reopening 700-900mb, then >1gb. After disabling “Show backup status icon on files and folders” in Mozy the memory leak disappeared and performance was back where it should be. Thanks to Herman ;-).
Btw it wasn’t necessary to disable Mozy’s virtual drive.
Had the same performance issues as you guys. I have a Q6600 quad core Vista x64 box w/4GB memory. Here is what I found (Mozy support was useless):
- The Explorer.exe process was using apx 3GB of my 4GB of memory causing everything to page out and bring the system to a crawl.
- Mozy created 25,000 – 30,000 temp fiels in C:\Windows\Temp
- Once all the system memory was used the backups would stall and whatever Mozy was trying to do would also come to a crawl.
- Mozy support had no clue, I provided all these details and screen captures and they had NOTHING to say. Mozy finally finished doing whatever it was doing and things are back to normal (The temp files are gone).
- As per your guys suggestion I’ve now turned off the icon notifications, I’ll see how that goes.
I have 2.2TB of data and 700,000+ files.
Have seen this issue with alot of companies time and again. I use backazon.com for all my online backups now. Secure Amazon S3 server and actual LIVE USA based customer support. Great stuff
Cheers

Going crazy trying to get this answered. CARBONITE forces you to individually select any video files you wish to back up. That’s a deal breaker for me. Does Mozy make you do this or do they actually back up all your stuff?
