Windows 10 hangs up frequently

about CrashPlan · · 2 Helpful

I have been using CrashPlan for more than 6 months. It works but it is too CPU intensive for a background desktop backup solution. I would like it if it were more lightweight. My Windows 10 hangs up frequently when CrashPlan is running.


Working for me

about CrashPlan · ·

I use this to backup both Windows and Linux PCs to multiple locations, including CrashPlan's servers. It works well for me on both OS's. I had to make a couple tweaks to get it working right on Linux (increased shared memory allocation, see their FAQ) but after that it runs great. No problems with failed/incomplete backups so long as the computers are left on long enough to allow them to complete. Migrating backups to a new computer is also straightforward and accomplished using the GUI. There's also an Android version that allows me to download backed up files to my phone--very nice!

A good backup solution should work effortlessly and silently, but fail loudly. It should just work out of the box or else you'll need to spend lots of work getting it up and running, which means you'll go without backups until then. You also don't want a false sense of security, thinking it's backing up and then your computer fails and you realize it was never backing up correctly. So far, it seems CrashPlan is not a good backup solution on Linux.

I've been trying to get it to work for a week now, with 200 GB of files, and it still hasn't completed a single backup to any destination, even to my own computer over a 100 Mbit/s LAN connection.

The Linux installer is terrible. To install this on Linux, there's no .deb, PPA, repo, or anything. You have to download a .tgz file, untar it, and run a ./ script. The script then asks user-unfriendly command line questions like where you want to put the executable and how you want to start it at boot. At least it has defaults.

Then the install script won't work if you have a non-bash login shell, like fish.

Then the uninstaller doesn't remove all the files and the dumb installer refuses to re-install because there are still files left on the drive by the uninstaller.

Then if you try to archive to an external drive, CrashPlan starts at boot, doesn't see the external drive, and forces the creation of a new folder where it used to be, and starts over again, filling up your root drive until your computer locks up. It's really stupid.

CrashPlan says to work around this by telling it to backup to a subfolder of the disk rather than the root of that disk, but this doesn't actually work. It still filled up my root drive, just at the subfolder location instead.

Setting the Default backup location isn't enough to change this anyway. You have to actually click the name of the backup (which is not obviously a link), and then there is a separate place to set the backup location in there.

And why does the "Files" section of the client always say "Scanning" and rarely shows the size of the backup correctly? Are they literally scanning every bit of the entire set of files over again every time you load the control panel, instead of just watching for file modifications on the OS level? Is that why my computer's been so laggy and slow for the last few days?

It's cool that it automatically connects to another computer even over the internet, with no special configuration.

The backup to their servers, on the other hand, is insanely slow. I'd tell you exactly how slow, but it stopped telling me the actual value for no obvious reason.

The information about ongoing backups is very confusing. Sometimes it tells you the status of the backup, transmission speed, and how much time it will take. Other times it just says "sending" with a filename and no other data.

On the website, it says 62% complete of my 200 GB? But on my client, it says "Space used: 4 GB". Then they send me a Backup Status Report by email that says my cloud backup is 1.7% complete. WTF?? 4 GB per week is... 0.05 Mbit/s. Something is wrong.

Apparently, they've lost their customer's data more than once:

And their response? "This is part of the reason that we highly recommend that you use CrashPlan to backup to more than one destination (i.e. another computer or an external harddrive)."


I don't understand why in the world anyone would pay money for their cloud storage service when it's slower and less reliable than backing up to a friend's computer for free.

So I kept getting emails from them that my computers weren't backed up, so I went on their website to delete my computers and my account. (I have started using Backblaze instead.) Apparently there is no way to do this. You have to delete computers from within the app itself. So I installed the application again. As soon as I have done this, my computer starts locking up every few seconds. :D Then when I try to log in, it crashes. Nice.
