When going to Admin>System>Tools>Backups, the following error gets generated:

There has been an error processing your request 
Exception printing is disabled by default for security reasons. 
Error log record number: 1295409723488

I have looked at the report, var/report/1295409723488 and it doesn't make any sense to me. It talks about Item (Varien_Object) with the same id "2015_db" already exist". Is this in a database table?

I used to use Admin>System>Tools>Backups to get all database backups, but it was recommended NOT to use Magento's backups and perform database backups through SSH instead. So I moved all my previous backups to a folder called "Older_Backups" under var/backups (via ftp), to move them later on to my local storage.

Now when I go to Admin>System>Tools>Backups it displays the above error.

Error log record number: 1295409723488 displays about 36 lines.
Here is the trace:

I did delete all cache, but I'm getting the same error. Otherwise everything else seems to functions properly. What could be causing this?

  • Ok I found out what causes the error: (Varien_Object) with the same id "2015_db" already exist".This error is caused by the name of the backup files! My cron job generated two backup files. The file names started with -%p%Y%m%d-%H:%M:%S.Generating backup files, similar to -20150705-11:30:15.gz and -20150705-23:30:15.gz. When going to Admin>System>Tools>Backups after the second backup is generated, it sees the first n characters of the backup names as the same ( -20150705). Hence throwing the error: "-2015070606_db" already exist". I am trying to find the best way to name them. – user2774042 Jul 6 '15 at 13:53
  • The other issue I noticed is the date on the server for backup files are correct 7/5/2015, but in Admin>System>Tools>Backups the date is shown as some off date in 1900s (Dec 31, 1969 4:00:00 PM) Can not figure that now. – user2774042 Jul 6 '15 at 13:57
  • Magento uses the Unix/Linux timestamp for the file name prefix. – user2774042 Jul 6 '15 at 14:50
