Hello this is exellent script, but i have one problem. On the last stage of the script trying to delete old dropbox files, i get:
"Deleting "/backup-2017-09-12_143059.sql.gz"... FAILED"
"Deleting "/backup-2017-04-12_123047.sql.g"... FAILED"
"Deleting "/backup-2017-02-12_113032.sql.g"... FAILED"

Why the script failing to delete old files?

Hi there. I have found your script to delete files older than xx days in dropbox using the dropbox_uploader script, but I cannot get it to delete files in drop. I have modify your script to download backup zip files. The script uploads the files to dropbox, but it doesn't delete old files in dropbox. No errors or any line that says it is deleting....... When you have the time, can you take a look at the code? Thank you.
