A replacement for CrashPlan

Tuesday, August 29th, 2017 at 10:16 pm

For a number of years I have been using CrashPlan for backups, so it was a bit annoying to find out last week that it will stop working in a year’s time.

My initial setup involved three computers and two external hard drives:

  • linux box acting as a destination
  • my parents desktop backing up photos/documents/etc over the internet to my linux box
  • my windows desktop backing up photos/records/documents to both the my linux box (which it was sitting next to) and the two external hard drives (one of them kept off-site)

This worked ok, but it had issues. The first (and biggest) being that the upload through my parent’s cable modem could make my adsl connection unusable, so the first change was to pay for a subscription to have my parent’s back up to the cloud. The initial sync of around 100 GB took a while but then worked nicely. (works even nicer now that they have NBN…)

The only issue I had with the linux install was when it failed to update itself. I don’t know how often there were updates, but I know that four times it would get into a loop of downloading the update, failing to install, downloading the update, etc. This would continue until the 10GB root partition would fill up. Each time I would delete the update files, open the app and manually trigger an update.

The pair of external hard drives started out at 500GB, were replaced by a pair of 1TB drives, and then at the end of last year replaced again by a pair of 2TB drives. I keep taking photos, at 25MB per raw file it adds up.

I am also slowly getting around to replacing the current linux box, so I am getting rid of some things to simplify matters. The two external drives have been sufficient, the only trick being remembering to plug one of them in (usually after coming back from taking photos somewhere), letting it sync and then swapping it with the other one which I have been keeping at work.

So now I am being forced to change…

My parent’s desktop is going to be easy as a quick look around shows that backing up a single computer to the cloud is the common use case. Their current subscription expires in February, so I have six months to find an appropriate plan.

Backing up my data isn’t as straightforward, largely due to the quality of internet here in Australia, the reason that I have stuck with a pair of external drives.

My ADSL connection is better than it used to be (almost double the speed and reliability once a tech redid the connections in the junction box out on the pole…), these days around 7000kb/s down and 800kb/s up.

I have 1TB of photos, so over four months for the initial upload to a cloud service. When I take photos I come back with a lot of them, they get culled but the backup is before that. I can easily take 400 photos in a single day, which is 10GB or more than a full day to backup. I can’t see how a cloud service works for me with ADSL.

(But what about NBN? It is available to all of the houses around me, but I’m in a unit which appears to be being left until later… even then I don’t know what tier I am prepared to pay for. I should be able to pay the same as now for 25/5 or $20 more each month for 100/40, these work out to be 5 hours and 30 minutes for that “day” of photos)

As I start to look for a replacement I have been thinking about what I want:

  • local non-cloud and free
  • specify folders to monitor
  • target is multiple external drives
  • service that detects when external drive is connected
  • revision history (not just a basic sync, can recover deleted files)
  • data deduplication (no duplicates when files moved around or renamed)

I have a year until CrashPlan stops working, I wonder what I will find…
