Re: Backups not working after running out of space

[qx6uwumzvv]

FWIW, my script(s) run "df -h" on the volume (as suggested in the FAQ 
entry) before and after so I can see the effect of my "remove increments 
--older-than 1Y" and "backup --print-statistics" invocations, so I knew 
was down to 5% free, but I also (thought I) had a good idea of the rate 
of growth, so I wasn't tooworried. Unfortunately, a software update (to 
Adobe Lightroom) caused the size of my sourcedir to increase way more 
than usual, resulting in a much larger than usual increment and 
targetdir running out of space.   The frustrating part is that the new 
version of Lightroom has a bug 
(https://community.adobe.com/t5/lightroom-classic-bugs/p-local-adjustement-preset-incorrectly-listed-in-the-history-panel-as-mask1-update-point-colors/idc-p/14222414) 
so I reverted to the previous version after a couple of days.

Your tools/misc/verify_disk_space.sh script is a great idea.  I'm going 
to incorporate it into my backup script(s).

Thanks for adding it and announcing it here.
