lofty-rs VS dano

Note: For audio tags there is a great rust crate called lofty

You should check out my program dano. It has a dupe detection function.

dano is a wrapper for ffmpeg that checksums the internal file streams of ffmpeg compatible media files, and stores them in a format which can be used to verify such checksums later. This is handy, because, should you choose to change metadata tags, or change file names, the media checksums should remain the same.

dano - a hashdeep/md5tree (but much more) for media files

My best advice (from a person who knows only enough to package his own projects) is it depends on the project. For my own Rust projects, I've found a Debian autopackager called cargo-deb for cargo. I convert those deb packages to rpm with alien. I upload both to the repo manually, and have a script which generates what I need and uploads to a PPA.

The meaty part of the holidays comes a little early this year for Ubuntu/Debian users, as I've prepared a special treat -- a PPA for httm (and dano)!

If you use something like ZFS, then you have a system thats watching your entire data path. If you're not paranoid, afraid of other ways your data can be corrupted, bit rot, etc. (again you do you), you might still want to look at a program I wrote awhile ago, dano, and have a system to periodically verify the data on disk.

One thing ZFS doesn't do (and thank goodness it doesn't?), it doesn't detect out-of-band changes to files. If a program has the permissions to modify a file, ZFS happily modifies that file. But, for some files (and for the truly paranoid), we may want to keep additional metadata about file integrity. For instance, FLAC files keep checksums of its music streams. A program I wrote, dano, provides a way to do the same for all FFMPEG compatible media streams.
