I use OSX/macos. For years, I have backed up files to external hard drives either directly attached to my computer or to my home router using rsync. Essentially, I get verified copies (which can be incremental backups). However, restoration is purely manual.
Now, I am looking for an alternative that (1) each family member can use on their own (2 high school kids and wife), (2) may backup to external hard drives at home and maybe in the cloud in the future, (3) may be scheduled to run periodically, and (4) includes restoration capability.
One other user is on macos, and the other 2 are on Windows 10. Each of us will have our own “free-standing” backups, i.e. backups are isolated even if they may contain identical files, such as a family photo.
Having spent the past hour perusing this forum and the Duplicacy guide, it is not clear to me whether or not Duplicacy fits the bill.
How does Duplicacy verify accuracy of backed up files? Do the backed up files retain all of their original properties when restored (e.g. extended attributes or alternate data streams)?
What about incremental backups? It seems that incremental backups are maintained through Duplicacy revisions. How many revisions are maintained, i.e. if I delete a file from the Documents directory, how many backups can I perform before the deleted document is no longer available in any snapshot?
About licensing - under Licensing Exceptions is stated “GUI/CLI licenses are not required under the following situations:” - one of which is running the CLI to back up personal files on an individual home computer. Is a GUI/CLI license required, or not? Apparently, a CLI license is never required for personal non-business use, so is there an exception for the GUI? (I’ve installed Duplicacy on my Mac without any apparent option for license exception).
