Hello. I need that during today's backup, the metadata about the files is saved in a file, so that tomorrow when creating a backup with the option "link-dest" instead of this option I would specify a file with metadata, then rsync will not scan the folder specified in "link-dest", but simply reads information about this folder from a file with metadata. This greatly saves time and load on the server with backups.
I do not delete through rm -rf, but delete the ZFS partition, you can also delete via find -delete, there are other ways On 26 июня 2018 г., 22:47:56: > I don't believe there is anything you can do with the batch options for > this.
