Who are we?

We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

We are one. We are legion. And we're trying really hard not to forget.

  1. I like Incremental backup methodology, but it needs frequent full backups (as i understand from "grandfather,father,son" method), How to have version control where i only create full-backup only once ?

  2. and I can choose to Delete changes older than 1 month.

  3. How to Only backup Select Data, like only personal data,

  4. and a "Ghost" for other data. Ghost is only filename and it's metadata (also folder structure). Data selected for Ghost is from internet which can be downloaded.

  1. "file change tracker" to see summary of what files are moved/deleted/renamed.

  2. "File History" where I see previous version of files.

Software ?

  1. Seems like https://restic.net/ is best as it's enterprise trusted works on all OS,

How do I set it up like I described in the Original Post.

I have a external disk and internal HDD, I want to backup select data, to a 3rd disk, both backup to the same disk, both separately backup-ed.

Look at block-based backup solutions like restic . Also popular is borgbackup .
