How can I improve restore robustness and execution times?
Moodle1.9 To improve restore robustness and execution times, particularly for medium to large course backups, try enabling the setting experimentalsplitrestore in Administration > Miscellaneous > Experimental. (This setting is available in Moodle 1.9.5 onwards.) MDL-18468 contains information about this Experimental Split Restore functionality and the improvements to course restore robustness and execution times that it introduced, particularly for medium to large course backups. It also explains why this is an ‘Experimental’ feature in Moodle 1.9.
