Timeshift's Absurd Space Requirements?

Post by VtPoet » Thu Aug 23, 2018 7:30 pm

Why does Timeshift demand over 260 Gigabytes of free space for an installation that only uses 26 Gigs?!? All home directories are excluded.

Wow - only 260 GBs??? :wink: Mine never gets higher than 2x the size of / (the only partition I'm using it for). Can you paste your snapshot configuration - I'm mainly interested in the schedule and the number of snapshots to save.
Mint 19.2 XFCE
kernel 4.15.0-64-generic
AMD FX-8350 Eight-Core w/16 GB RAM
Nvidia GeForce 960 w/2GB RAM (435.21)

Nevermind, I figured it out. When I installed Mint, I formatted a secondary partition and called it "/storage". I use this for my home directory via symlinks. Once I filtered out /storage/**, the absurd space requirements went away.

This is interesting because everything on storage is, in a sense, the home folder. In other words, my Documents folder is symlinked to the Documents folder in /storage. The reason I do this is for installing new Linux Distros (though this time I simply upgraded Linux Mint). It makes installing new OS's much quicker and easier.

Even so, TImeshift apparently doesn't consider all those "home" folders to be excluded because they are not, technically speaking, in the excluded home folder. Probably wouldn't call this a bug. Kind of a gray area.

Edit: I don't make the second partition my Home directory because then I'd have to weed out all the distro dependent config files when installing a new distro.

Timeshift only automatically excludes mounts in /mnt and /media, everything else is your own responsibility to exclude.

Not true. On both my mint installations, Timeshift automatically excluded all home folders.

Timeshift excludes a whole bunch of folders, but as far as arbitrary mounts go only /mnt and /media as the default mount points are excluded. You can get the full list of what's going on by clicking on Timeshift > Settings > Filters > Summary.

Wrong. The post says "excludes mounts" <--- mounts.

Wrong. The post also says " everything else is your own responsibility to exclude. " <--- everything else

That's demonstrably not the case. On the both my mint systems my Home folders were also excluded. Ignoring this is to play semantics.

On the contrary. I was pointing out where the emphasis is. If there was an error, it was only in omitting the two mount locations.

That's demonstrably not the case. On the both my mint systems my Home folders were also excluded. Ignoring this is to play semantics.
Let's play:
semantics
/sɪˈmantɪks/
noun
the branch of linguistics and logic concerned with meaning. The two main areas are logical semantics, concerned with matters such as sense and reference and presupposition and implication, and lexical semantics, concerned with the analysis of word meanings and relations between them.
So semantics are what's needed to understand what another person means. If you refuse to play semantics you basically saying you refuse to understand.

Now semantics include context, and the context of my statement was clearly mounts, in reference to your /storage mount not being excluded. You can drone on about your home folders - which are not mounts - all you want, it really is besides the point I was making and that others clearly understood.

Anyway, I only responded because of your statement about semantics. At the end of the day you do you and I really don't care. :)

Yeah. You looked up the wrong definition, the definition you should have looked up is "playing semantics", not "semantics".

What I was responding to was this:

"Timeshift only automatically excludes mounts in /mnt and /media..."

And for the sake of accuracy: This is simply wrong. I can't speak for Timeshift on all distros, but on both my Mint distributions TImeshift also *automatically* excludes the systems /home folders.

SO WHAT!?!

"User home directories are excluded by default unless you enable them here."

Tell me what part of that you don't get and we can proceed if you want.
