When I do either a scheduled or a manual backup, that's all I get. When I also write to NodeSquirrel, the NodeSquirrel backups are fine.
The problem started when I moved the private file folder to a level below the Drupal user "home" directory (it's a CentOS/cPanel server), to avoid these backups getting added to the overall server backup files - or so I originally thought (see below).
I've since figured out that I can exclude the files from the backup via a script. I pointed the private files directory back the original directory (one level below the web root), but I'm still getting empty files, even though Backup and Migrate sends me messages that the backup completed successfully.
I've checked permissions; I can manually write to that directory as the Drupal user (via nano). Anyone else experienced this?
Now when I back up the database ONLY, it works as expected. I actually get a compressed .sql file that looks like what I'd expect. But when I try to back up the public files directory, it reports "Public Files Directory backed up successfully to XYZ-2016-12-20T22-20-22 (444.61 MB) in destination Manual Backups Directory in 7 min 42 sec." However, this is what's in the directory:
-rw-r--r-- 1 dUser dUser 0 Dec 20 22:28 XYZ-2016-12-20T22-20-22.tar.gz -rw-rw-r-- 1 dUser dUser 0 Dec 20 22:28 XYZ-2016-12-20T22-20-22.tar.gz.info
Have altered max_execution time in php.ini, and tried changing dir permissions to 775 and ownership to dUser:webserverUser to no avail.
Next tried drush bam-backup files. First time I got "Unable to create or write to the save directory 'private://backup_migrate/manual'." (!!!) And drush was operating under root! So I changed permissions to 777 on the whole directory structure and the drush back up was successful, but why? It did kick out an error, though: "Error while sending QUERY packet. PID=7537 database.inc:2227".
So now I'm quite confused. Was it one of the updates I did to Drupal core? I don't believe the backup_migrate module had an update in that time frame.
TIA for any insights or advice!
