First of all, I'm aware of threads like Comparison of backup tools.
With that in mind, I have a specific set of requirements for backup, and I was wondering which are the current options - the informations around are fragmented and confusing, especially considering that online drives are not backup solutions.
My requirements are the following:
- be able to backup individual files (ie. no dejadup, thanks)
- cloud storage (upload of an intermediate backup archive is not viable)
- have a daemon running in the background, backing up at least at time intervals (optionally, having a continuous backup)
- no need to setup a server
- file versioning
- ability to handle large data sets (number of files rather than space)
- ability to backup drives that are not guaranteed to be mounted, without hassles
Optionally:
- restore from the backup structure of a given point in time. this is different from restoring from the current backup tree, with the option of choosing older versions.
- reporting
Price doesn't matter.
Excluded solutions:
- JungleDisk was perfect, until the moment it's been discontinued.
- SpiderOak is really badly coded; It has annoying bugs, and it hangs on large number of files. Also, if a drive is not mounted when SO starts, it won't be backed up.
- Symform has a bug in the registration. Since you can't contact support without registering, it's completely useless.
