Inactivity Backup Errors


1. Trying to create backup archive …

Set for 3 retries… This means the backup archive was Not created, right? In the backup folder, are numerous 0-byte files.

a) Say clearly “Backup archive not created”
b) How do I set the timeout?
c) How do I estimate how long the timeout should be? (E.g. given how much was archived in 5 minutes, how long would the entire archive take?)
d) I want to back up all the files of my site, excluding folders with huge files (audio, video I can back up separately). The resulting file size might be over 2GB. If just a small Multi-Site blog takes more than 5 minutes, the full backup needs a Much larger setting!
e) Archive pieces are left in the backup folder. Are these useable? File names such as backwpup_1_2013-08-13_23-21-07.zip.Polk1B or backwpup_1_2013-08-13_23-21-07.zip.aZzqDu

I have added to my wp-config this line:
set_time_limit(3600); /* 1 hour */
This should be in the plugin, set before each database or ZIP operation: set_time_limit(600); // 10 minutes

@obit8 No, the set_time_limit in wp-config does not work, I was stating that I had tried it. Setting the overall WordPress time limit to 1 hr is of course defeating the purpose — it is to allow PHP to stop processes that are out of control. PHP allows specifying the timeout so you can give things like database queries that could take a little longer, or making .zip files which could take a long time, enough time to complete; that should be done in the plugin surrounding the specific time-consuming steps.

I also have problems with WordPress plugin updates not unzipping, so there may be a problem with the zip functions on my WordPress, or my server, or some other plugin conflicting with zip, or…. I don’t really have a way to test it, until I dive in to learning to write a PHP zip routine…

Somewhere I posted that the tar format (no compression, just put everything in one file) worked for the database backup but not for “database plus all my folders”
