I'm looking for a reliable backup solution on Windows, something with a feature set similar to Yadis.
I've been using CrashPlan for 2 months, but their software lost more than 1TB of my data, that's why I'm looking for alternatives.
- Real-time local folder-to-folder backup
I don't need online features, I want to use this to duplicate my files between my local disks.
- Versioning support
Should be able to choose how many versions to keep of the files.
Or at the very least, it should keep deleted files until a specified time or space limit gets hit, and delete them afterwards automatically.
- Plain backup
I want to be able to open the backup without special software. No proprietary file formats.
- Shadow copy
Backup every file, even locked/system files. (Yadis fails this one)
Doesn't need to run as a service, but that's a plus.
- Actively maintained
I don't want to use discontinued products.
- Relatively cheap
Should be under $100 for one-time payment, or $60 for a yearly fee.
- External disk support
Shouldn't have any problem using external disks, at least on the source side.
- Low resource usage
I'm not really comfortable with something that eats 1GB of my RAM.
- Compression support
Preferably ZIP, but I'm not picky about this. Any ordinary everyday format is acceptable.
- Freeware or Open Source
- Linux support
- Cloud storage
