Snapshot Pro breaks...

Hi, I tried to use Snapshot Pro to do a backup. All went well until it starts to backup files. Then it breaks saying it has maxed out the memory. In fact, I've had same experience on more than 5 different websites that I tried to use Snapshot Pro on.

And then I switch to All-in-one WP Migration, and the backup went well. So I am confident that it's not my server's problem. Please advise.

    Hello Lam Woon Cherk,

    If error you see says maxed out memory then it is possible that you will need to increase memory limits https://premium.wpmudev.org/blog/increase-memory-limit/
    Your current limits can be found in WPMU DEV -> Support -> System Info.

    Reason why another plugin works is that they don't need more memory and their process of making of backup is different than in our plugin.

    Can you tell me if backups that didnt work were managed backups or standard backups? could I see issue on your site - would you mind allowing support access so we can have a closer look at this?

    Hi Lam Woon Cherk,

    So there the server definitely has no problem

    You are absolutely right. Your server doesn't have any problem in general. But suppose, your server has 1GB of memory allocated, but you a process which requires 2GB memory at least. So for that particular task, your server will give error because your server can't provide enough memory to that specific task.

    As you said it always happens when the backup process reaches the file step (I believe, more specifically the "plugins" folder step), I believe, any of you plugin has somecode or very large file size or something which might be causing this.

    Just to make sure this is not happening for any other specific plugin, can you please do a plugin conflict test? To know more about plugin conflict test, you can check this guide: http://premium.wpmudev.org/manuals/using-wpmu-dev/getting-support/

    I believe, in this way, you can find out which specific plugin is conflicting with the Snapshot backup process.

    And regarding the memory issue, can you please try following the guide Kasia mentioned above? https://premium.wpmudev.org/blog/increase-memory-limit/

    I believe, these will resolve your issue with snapshot. If these don't, would you mind allowing Support Access so we can have a closer look at this?

    To enable support access you can follow this guide here:
    http://premium.wpmudev.org/manuals/wpmu-dev-dashboard-enabling-staff-login/

    Please let us know the result of your plugin conflict test and confirm here when you are done granting Support Access (if the issue is still not resolved). I'm looking forward to hearing from you and resolving this issue as soon as possible.

    Have a nice day. Cheers!

    If some other backup plugins can handle the same site without problems, I don't find why Snapshot cannot? If snapshot cannot work in more than 10 websites that I've tried, what's good about the plugin?

    I doubt this is the case, because I've tried Snapshot on more than 10 client websites, each of them having very different plugins installed. And it didn't work a single time after 10 attempts on different sites, I don't find the point of using Snapshot.

    And regarding the memory issue, can you please try following the guide Kasia mentioned above? https://premium.wpmudev.org/blog/increase-memory-limit/

    I suspect you've read my earlier reply, because I have attached a screenshot showing the memory limit is 512M.

    Please let us know the result of your plugin conflict test and confirm here when you are done granting Support Access (if the issue is still not resolved). I'm looking forward to hearing from you and resolving this issue as soon as possible.

    Again, I suspect you have read my earlier reply, because I specifically mentioned that I've granted you access. Are you using some kind of canned replies? This is not helping at all.

    Hey Lam Woon Cherk,

    Hope you are doing good today. :slight_smile:

    If some other backup plugins can handle the same site without problems, I don't find why Snapshot cannot? If snapshot cannot work in more than 10 websites that I've tried, what's good about the plugin?

    Sorry for any confusion, I do understand what you are trying to say, but it's pretty tough to tell why Snapshot is throwing internal server error when you take backups, without troubleshooting the issue further. We could only comment further about it, only if I could zero out on what's exactly the problem. I could see support access enabled for http://old.mbtaxcxxxxxxxxxxxxx.com

    I checked your website, and I could see that you have other 3 backup plugins enabled, If I disable the other backup plugins, the memory limit, and max_execution_time is showing conflict as seen in the screenshot below:

    And once I disable all the plugins, I get memory limit as 256M.

    So it seems like you are increasing your memory limit with the help of plugin? Could you please increase your memory limit in your server, instead of using a plugin? So, I wasn't able to perform a full plugin conflict test because disabling the plugin, will decrease your memory limit from 512 to 256M.

    To check why Snapshot fails, I would like to enable debug mode in your system, so that we could have a better idea about this. You can find more details about debugging here.

    Could you please send us your credentials, so that I could enable debug mode, and could give a closer look at it. You can send credentials by using our secure contact form: http://premium.wpmudev.org/contact/

    I doubt this is the case, because I've tried Snapshot on more than 10 client websites, each of them having very different plugins installed. And it didn't work a single time after 10 attempts on different sites, I don't find the point of using Snapshot.

    We just want to make sure whether we don't rule out such issues. The internal server errors, doesn't tell us anything much, as it's more of a general error, and we would like to be sure that there isn't any plugin conflict. I do understand you have different plugins in all your different site. At the moment, it's better, that we could focus at your current website, so that it would be easier to sort your remaining websites.

    Please do fill me up with the credentials, so that we could help get this sorted. Have a nice day. :slight_smile:

    I didn't do anything specifically to increasing the memory limit. It may be one of the plugins that I am using that is doing it automatically.

    Contacted you with the info you need as instructed.

Thank NAME, for their help.

Let NAME know exactly why they deserved these points.

Gift a custom amount of points.
