I have a Windows server that I use as a development and testing server. Besides that it also hosts my Subversion repository.
Being a developer, my subversion repository is of great value to me. I have therefor been looking for different online backup providers. My requirements are:
- Must run in a Windows server environment
- Preferably free or rather cheap
- Must run autonomously
- 2-3 GB of space
- Low frequency of errors
Dropbox provides you with a 2GB free account and works both for Windows and Mac. However it only supports backing/synchronizing one folder.
SugarSync is actually ok and has a nice IPhone app. They provide a 2GB free plan, and I am currently using them in another context. However, they are a bit pricy compared to others.
They also provides you with a 2GB free plan. They work alright and have some friendly support people, however their Windows application seems buggy. I have tested the application on 3 different Windows machines, and at first everything works fine… but at some point the software just stops backing up. It seems like the schedule part is broken.
The free plan can also be used on Windows server versions, which is nice.
Mozy provides, like the rest, a 2 GB free plan. The software works fine, however not on Windows server versions.
Another thing to note is, if you need to backup a large number of files then Mozy will consume a large portion of you memory accordingly. I have experienced Mozy consuming 400-450 MB of ram.
After testing the other providers I found Memopal. They provide a 3GB free account, which is more than the others. Their application runs among others on Mac, Linux and Windows, including a server environment.
As Memopal initially almost satisfies all of my requirements, I was hopeful Unfortunately Memopal would not back files up larger than 20MB, as their limit should be 5GB per file, it must be some kind of error with the software. All the smaller files were backup without problems.
As I was backing my Subversion server files up some directories are just called “0″, “1″, “2″ etc. it looks like Memopal does not support these folder names, I was not able to retrieve these folders from their web interface.
So this leaves me with nothing… or I am settling with IDrive and hoping that the errors in the software will be fixed. But I will keep looking for a good and reliable online backup software.
