Hello,

So I have Time Machine backups on our Mac Studio backing up to our
Synology DiskStation. But now I'm puzzled.

It has the option to back up hourly, daily, or weekly. Hourly is too
much, and daily is too little -- I'd like to back up every 6 hours.

Is there a way to set that up in the gui, or do I need to set up tmutil
jobs in crontab? Or...?

Thanks,

No.

Time Machine backs up every hour.

What you are looking at is how it culls it's backups.

I use TimeMachineEditor to set my own schedule of when Time Machine runs.

https://www.macupdate.com/app/mac/26704/timemachineeditor

You turn off the automatic scheduler and set your own using the Editor. It creates a Launch schedule to at specific intervals or on a calendar intervals. I currently take Time Machine backups at 3 hour intervals throughout the day.

The initial thought for the built-in schedule is that TM would run hourly during "normal working hours", then infrequently after hours. Backups older than 24 hours are consolidated to a single backup. Backups older than 3 months are consolidated to weekly backups.

Apple has articles on how it runs on their site and this article goes into
more detail. Howard also has utilities to check Time Machine.

Unless I'm mistaken, that turns out not to be the case. If you
look under "options" in System > General > Time Machine, you'll
see four options for frequency of backup: Manual, Hourly, Daily, Weekly.

I set it to "Manual", then used TME to set backups for every 6 hours.

Thank you very much. No trouble installing and setting up TME, once I got
past the annoying ads on macupdate.com. (Among other things, it tried
to get me to install Avast -- are you kidding me? ;)

Hourly isn't too much. 🤣 Hourly backups let you undelete files you just deleted, or roll back to a version of the file you modified. And an hourly frequency means incremental backup will be smaller and faster. So I
really have to wonder what makes you claim they are "too much"...

It never ceases to amaze me how many people are just bumbling around the
web with no ad blocker... Bunch of masochists!

Ah!

I hadn't notice that option. It must be fairly new.

Especially when you realize that it does do backup culling to avoid
using TOO much storage.

Keep the HD plugged and it does not matter. The amount of data remains
the same. Hourly is a very reasonable period.

I agree in principle, but I get about the same changes every six
hours as every hour, since the Mac isn't used very often. There's
overhead in determining the changes to back up. I'd just rather
not run backups so often. TME is a good solution for that.

The backups were going to a Synology Diskstation. Finally decided
to speed that up a bit, so I got a nice 4TB NVMe/USB 3.2 drive,
a SanDisk Extreme Pro. Plugged that into my Linux workstation and
set up Samba for Time Machine. Now I use that for
Time Machine backups from the Mac, as well as Timeshift
backups from Linux Mint.
