Backup getting stuck at 65%, can be because of multiple reasons. All the possible reasons we have discovered till now are listed below with fixes.
List of Reasons are as follows :-
Memory Limit has reached
To solve this issue first we suggest you make sure that you are not backing up backups create by other backup plugins. Because a backup file could be of at least few hundred MBs which can require lot more memory to backup than single small files. So check through your installation to find files which are above 50MBs.
Once you find them and they are backup files we suggest you exclude them. You don't need to exclude Backuply backup files as they are always excluded by Backuply.
You can exclude a file by going to Backuply -> Settings and the Exclude block
If you don't find any big file in your installation then what you should do is increase memory limit of your server. You can try different limits but you can start with 512M and if that works you can try something lower than that and see if that works.
If even after updating the Memory Limit you are facing the same issue then you can add a Constant in the wp-config.php file.
if(!defined('WP_MEMORY_LIMIT')){
define('WP_MEMORY_LIMIT', '512M');
}If this doesn't works either then try to solve the second issue we have mentioned which is the security configuration options.
Security Options
It's possible that if you have enabled security options like ModSecurity or Immunify then they might be blocking the backups or even restores.
What you can do is disable them and then try to backup or restore. See if it works.
If it still doesn't works then contact out support team we will help you out. You can write to us at support@backuply.com
