Are partial backups to the same folder OK?

[Илья Палий]

Peace and love, folks!
 
I plan daily backups of «/home» directory, excluding some parts like program 
settings (~/.config, ~/.local etc.).
 
And (maybe to the same target directory?) weekly backups of some of those 
settings, omitted in daily backups.
 
In other words, daily backups with some «holes», and then weekly backups partly 
filling those holes.
 
Is that OK? Or could there be some side effects of writing different backups to 
the same directory, and it’s better to send them to different directories?
 
Something like, daily:
rdiff-backup -v 5 --api-version 201 backup --preserve-numerical-ids --exclude 
$HOME’/.*/**’ /home/ $TARGET
Weekly:
rdiff-backup -v 5 --api-version 201 backup --preserve-numerical-ids --include 
$HOME/.config/autokey (and the like) --exclude $HOME $TARGET
 
Thank you :).
