412 will resolve the error in question, but just to inform you the script made it to that point because it found you did not have enough free space to complete the backup. The next line after the failure would have produced the error to inform you of the space issue. You will need to clear some free space on your disk before backups will complete.

You can try sudo ds -p or install ncdu and locate files taking up too much space.

Thanks!

Hmm... did I close this one too early. What's the correct workflow? :)

Veronit commented 5 years ago

How much space does the min one need? If it only backups the .env file, I thought it wouldn't need much. The previous lines before the error states that I have plenty of space available:

Ok, that error should now be fixed. The free space just needs to be above 5MB, and it looks like the script is actually reporting the size in kilobytes rather than megabytes, so when you see above 2258 free it's actually reporting in kilobytes and needs to be over 5000.

Thanks for the info.
