If it take my time to test a new software you can be rest assured that I do it thoroughly
But it's kinda moot since it doesn't backup anything other than your data by default.
Anything on my C: drive isn't data that should be backup-ed. Why not? I already decided over 20 years
ago that I separate all of my data from the partition, where the os is installed. Apart from that 95%
of my used software is portable and stores it's settings and data on a different drive (and the only
Software that needs to be installed is forced to write everything it wants to save to a different drive as well).
if you first just let it 'do its thing' to see exactly how long it took - and then logged in to check and see exactly what got backed up.
You don't need to. You can see this kind of information before it actually begins the real backup. Look at the last rightmost tabs.
I doubt you would have seen much there you wouldn't have selected anyway.
189 MB of files it wants to backup (only for the C: drive).
So once the initial mirror takes place, subsequent backups only require a fraction of the original time unless major changes have taken place on your local drive.
Delta-backup. Atm it's hard to find reasonable sync/backup providers that DON'T support this technology.
It also keeps deleted and changed files for up to 30 days - so it also acts as a sort of versioning backup system
That's the case, right. The currently used HiDrive account allows me to configure for how long old / deleted versions are kept and these settings can be changed for different folders and users (I use a 5 user account with 500gb of storage).
Regarding the huge amount of data that can be backuped with a slow uplink: I'm storing atm 150 GB on my user account at HiDrive. With non throttled upload speed this takes about 18 days (24h/day) if you don't want to pay the extra fee if you send in a hdd.
PS.: I like intelligent software. As long as it let's me reconfigure it's behavior when it does things that I don't want it to do.
