I have two family members backing up to my systems where I am running minio. This works. Both are still running older Macs. But one of these is very slow (30min-1 hour, both remotely to me (210GB) and locally (40GB) on a local hard disk) and the other is pretty quick (220GB remotely). The slow one even has a better internet connection. The only difference I can see is that the quick one has a lot more ‘changed data’ (I’m using duplicati-monitoring.com) that the other (250MB-500MB versus 5MB. So, I need to find out what part if the backup is causing these amounts of changed data.
What is the best way to find out what part of a backup is ‘changed data’? Some specific level of verbosity I can set to get to the bottom of this?
Did you mean to say the slow one has a lot more? Regardless, I think there’s no verbosity that gives per-file information on changed data, however there is a way to see what files are being added, deleted, or changed.
and then you must guess which files were the offenders in making a big upload. Note that the backup is on a file-block basis, and only changed blocks are uploaded. Unchanged blocks from old backups are referenced.
EDIT: A nicer web-UI-Commandline version from @kees-z (thanks!) of running a compare just went up here, for someone wanting basically the same thing (or at least giving them something that comes kind of close…).
