GoDaddy backup doesn't work for large files

I've been backing up zencart, but when I try to backup the entire store, or even just my image folder, I get a 500 error. backup files get created, but they can't be expanded. tried both locally, and on godaddy's file manager.
I changed the memory size to 1000 in the define in zc_backup config file like I saw in the zcbackup thread. using ver 1.1

If you are serious about your online business then why are you hosting with a mass marketed provider like GD??

GoDaddy/LuckyRegister is the worse Hosting Company.

If use Hostgator.com I have been using them for about 10 years.

Someone has to pay Danica's salary,,,
Now anyone able to help me out???

I'm not familiar with the zcbackup plugin's operation, but is it possible to do your export in pieces? That is, export only a subset of the tables at any one run.

There's one ZC backup plugin that backs up just fine. It just doesn't restore just fine. I used it for ages, assuming all was well until I needed to restore a backup and no luck.

That's why I only trust backups made using phpMyAdmin

Backup mysql using phpmyadmin (You can download one from official web site, check with your PHP version that have different version support on different PHP)

Download all file from your home by FileZilla with TLS enabled (Free) or any other FTP Client you like

Why this way? and not full auto script? If your server is not own by yourself, like rent by hosting company etc.
I don't believe their backup, manual full backup it by above two tools / way to your local computer will be your other safe belt if big problems happened.
Can do by daily for DB, weekly or monthly for PHP/images files etc.

And install ZC Plugin for backup, look like it is full auto and easy, but files still save in your hosting company remote server, it is down, you can access it files anymore, it is why I like full backup local.
