Magento backup problem

Magento 2
17

Looks like either:

  1. Magento doesn’t have permission to write to the default folder
  2. Magento doesn’t have permission to overwrite the logo_5.png file assuming that file exists already (perhaps owned by another user?)

When you upload via FTP are you using your magento user credentials? If you upload as someone else, it’ll break ownerships.

What output does the below give you?

ls -la /var/www/html/pub/media/logo/default/`

Best case scenario

drwxr-sr-x 2 www-data www-data  4096 Aug 21  2018 .
drwxr-sr-x 4 www-data www-data  4096 Oct 16 13:02 ..
-rw-r--r-- 1 www-data www-data  4211 Jul 17  2018 logo_5.png

Potential issue (wrong owner of existing file)

drwxr-sr-x 2 www-data www-data  4096 Aug 21  2018 .
drwxr-sr-x 4 www-data www-data  4096 Oct 16 13:02 ..
