Hi all,
I've been checking why my time machine has gone bananas with large backups that happen too often, but can't find an answer
I have my time machine on a network drive (WD My Book), so it back ups every night when I get home. Those are normally between 1.15 and 1.8Gb, which I find pretty massive considering that all my work is in the cloud (Google Apps, Figma), a bit of coding and mail. Hardly even open a file.
Those backups take normally 5-6 hours to complete, which makes me feel if my macbook is actually a backup machine that happens to allow me to do other work on the side. But the part that I find more bonkers is that as soon that 1.x Gb backup has finished, it starts a new one about 250-300Mb. Seriously? During those 5-6 hours I've only browsed a few webs and keep everything closed to ensure time machine runs as fast as possible. It has done that twice already this morning, with TM doing yet another one as I write.
So I've done tmutil compare and find out that TM considers that tons of files that I never touch have changed. For example apps I never use (VLC, iTunes), entire wordpress backups (with ALL the images) that I haven't looked at in years. Added /Library/cache/ and /Library/fonts, which is nuts because that's not new.
File is too big but here are some bits and bobs.
Any idea how to solve this madness? I'm starting to wonder whether it's WD's My Book, and I should do weekly backups on a wired HDD instead.
