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.
Requirements:
- 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) - AutoStart
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.
Optional requirements:
- 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
