Trying out minio as a backup destination

[AartJansen]

I have my own cloudron, and a customers, I have installed minio on my cloudron. And have configured my customers backup to use minio.
It accepts my configuraion, and begins... however I don't see anything inside the bucket, as the backup runs, and it eventually fails...

I changed the backup type to rsync and it appears to have worked. I can see that the backup takes up 314Gb on my server. But I would like to actually see the files somehow. its still not showing anything in the minio GUI view of bucket?

Hi,
find the solution here:

@CBCUN Thanks, found the advanced > part size setting. Have adjusted it, but maybe its not important now given that the default settings worked with rsync, and the following backups will be smaller anyway.

Still concerned the single bucket shows as empty.
EDIT: Scratch that. I logged out & back in and the web page shows the content.
