With PHP Version did you use and is it 32 or 64 bit ?

PHP Version 5.5.9-1ubuntu4.13
64-bit

For the lastes log set MAximum execution time to 30 secounds under BAckWPup > Settings > Tab: Job

I get the same error regarding size. I can run smaller jobs successfully, but one they get larger (i.e. 1+ gb) I get the below error. Any help is greatly appreciated! Thanks Daniel!

Please have a look in BackWPup > Settings > Tab: Information. what vor a bit version stands there?

I’m with GoDaddy. Would asking them to change any of these settings help with this issue and/or improve the overall performance of my site?

PHP version
5.3.24 (32bit)
MySQL version
5.0.96-log
cURL version
7.19.7
cURL SSL version
NSS/3.13.1.0

OK that the Problem you have a 64Bit OS with a 32Bit PHP! Than you can’t create backup archives over 2 GB. To get larger archives you must upgrade to a 64Bit PHP.
