Hi Eli,
Thanks for the detailed explanation, now it makes sense. I think it might be less confusing if the options are set like:
Backup every:____ hours (daily: 24, weekly: 168 cause it’s 24 x 7)
Number of backup files to keep: _____ (0 means infinite)
So there won’t be redundancy for choosing between hourly or daily backups.
Have a great day!
