Hi,
We are having the same issue, we have recently upgraded from 2.0.1 to 2.6.1 which seemed to go fine (2.0.1 - 2.2, then 2.2 - 2.6 as recommended), we had the previous backup issue with 2.0 where we had to keep changing the automated backup running status in the database back to 0 when it failed. But was lead to believe this was fixed since 2.1?
About 4 - 5 courses backed up for us when we first brought the new site up, all successful no errors in report, no errors in the .log file(s) in moodledata/temp/backup. Tried running the backup manually with the CLI - automated_backup.php and it says the backups are still running, same as the cron.php script.
Any ideas?
Brett
