In Plone 5 we used collective.recipe.backup and it worked great. But it is buildout based and for Plone 6 we were planning on eschewing buildout. Is there an alternative option? The docs are blank Backup and Restore – Deployment — Plone Documentation v6.0 on this topic.
I think all collective.recipe.backup does is create scripts in the bin directory. I haven't tried this yet but I am guessing I could probably just create my own script adjusted to any config changes, and without the buildout sys.path part.
In all our projects, we backup Data.fs + blobstorage completely every day...not entirely smart, but totally efficient and fool-proof...works for us with about 20 GB of data.
I know collective.recipe.backup uses rsync but I haven't looked into the details. I take it you mean you are running rsync commands directly without repozo?
