Personnally, I do a `check ::borg_archive` after each single hourly backup (on a not-always connected USB drive). I mean I don't decorrelate backup and check.
Since 1 backup+check takes (today) less than 1 hour it's ok but it's gonna be more complicated when it won't be the case anymore. Maybe  I will accept 1 backup every 2 hours, I don't know yet (repo is locked as long as the backup or check is not finished)...

If there is a best practice regarding checking, I will take it as well!

Try to put your 2 repos on different disks (different brands/models) and locations as well (in order to protect you against single point of failure - SPOF).
