Which Folders To Ignore In Backup

I assumed

var/cache

images/backup/

anything else?

/var/files/ has some files I think from export/import, safe to delete?

Be careful especially if you use EDP files. These are also stored in /var as well as other things like attachments, etc.

I would only exclude var/cache, var/upgrade, var/backups.

What about images/thumbnails ?

These are supposed to be regenerated, so no reason to add to backups?

Right. Thumbnails can be skipped

Thanks!
