We should also add a link to How to section.
How to "verify a backup"

• we already some references to pt-table-checkusm
  we can add a new subtopic here (may be?):

[Side topic]

Ideally, I would love to see all workflows in howto section. ie duplicating some links.
currently they are in separate binary sections for xbcloud, xbstream etc. Specially the streaming/cloud backups part.

We already covered good number of Howtos.. the list in my mind so far (including what we have right now)

How to
take full backup
take inc backup
How to verify a backup
How to know the size of backup [new feature]
How to take partial backup (partitions should go heere)
how to prepare backups (full/incremental)
How to restore a full backup
how to restore to incremental backups
how to restore a single table
How to stream a backup to cloud
how to download a backup from cloud
How to stream backups to another hosts
how to encrypt
how to compress
how to setup replica from a backup
How to tune xtrabackup (advanced): --parallel, --encyrpt-threads, --compress-threads, --fifo-streams, --parallel in xbcloud,
