Considering "snapper made too many snapshots and filled up my hard disk" is by far the #1 complaint from openSUSE users from the last few years, I would say that the features required to mitigate or remove this problem are most certainly required to be on by default on a user system.
and that would be good but TW default SPACE_LIMIT is set at 50%!
What's wrong with that? Available Free space isn't doing anything. Using 50% of the available free space seems like a very sensible default. As space of the active volume increases, that available free space will decrease, leading to less snapshots being kept around
over-the-top suse defaults have created and urban legend around the excesses of snapper. and all to achieve what in the typical use case?
You really need to ask that question? Snapper ensures the preservation of system state before and after any user makes any change in YaST or zypper in order to be able to rollback or selectively revert anything untoward that happened either during or after a user did something in YaST or zypper. IOW snapper's saves users from incompatible packages, packaging mistakes, software changing in ways the user doesn't like, user mistakes like choosing poor settings or doing stupid stuff like "rm -Rf" in the wrong folder An openSUSE system running snapper that works today is almost guaranteed that it can also work tomorrow, because of the certainty that you can rollback to todays state in the event of changes that break it.
this is funny [http://www.linux-magazine.com/Issues/2015/176/Snapper] "If you leave the default settings in the /etc/snapper/configs/root file, the snapshots will quickly consume a huge amount of space. A root partition, which can normally make do with 30GB, will need between 100 and 300GB of disk space for snapshots"
Not bad advice, but with the new snapshot cleanup by space feature a smaller root partition is again viable as we have a way of cleaning up based on available space, or snapper only keeps a number of snapshots which it has room for, not as many as it pleases. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
