EXTREMELY IMPORTANT: Please attach a ZIP file containing your Akeeba Backup log file in order for us to help you with any backup or restoration issue. If the file is over 2Mb, please upload it on your server and post a link to it.

Description of my issue:


Hi, I have two separate sites on the same server. The smaller site backup completes in about a minute (see attached log), although it generates a much bigger .jpa file than I expected.

The larger site does not complete. See the second log. It seems to be super-slow, and then spawns a second backup, and a third, and a fourth... Within a couple of hours, the server falls over because the disk is full. One day last week, the Akeeba log for the larger grew to 2.5GB.

I seem to have the same problem from the backend and from the command line.

Thanks.

Small site: I can see no problem

Large site: The log file attached is from a back-end backup, not CLI. The back-end backup seems to be killed by the host due to excessive resource usage, while backing up a huge CiviCRM database. Unfortunately we can't do anything about it except perhaps exclude the contents of civicrm_job_log table from backup.

Yes, I couldn't attach a CLI log file, because they are mega huge. I will work on reducing the size of the DB etc, and hopefully that should fix it.

For future reference, is there a way of aborting a cron job CLI backup once it has started? I had to re-boot the server.

To the best of my knowledge there is no way to cancel a CRON job once it's started unless you have SSH access to the server and a good working knowledge of UNIX, namely the kill and ps commands.

Yes, I could do that. Just kill the cron process? Or are there other process which would then also need killing?

Thanks.

The CRON daemon should not be killed. The CRON daemon should have spawned a PHP process and that's the one you have to kill. Using ps you can determine the pid of the PHP process and then kill it with the SIGKILL signal (SIGTERM will probably not work).

OK. Hopefully it won't be needed, but thanks very much for your prompt help. Jeremy.
