    Hi Seth Gitner,

    Hope you're doing well.

    If I understand correctly the issue here is that your backups are unable to finish each day, is that correct?

    This is most likely related to server not having enough recourses to finish at certain days and then when it has the backup finishes fine.

    Can you check your visitor logs and see if there is higher number of visitors at the times when backups failed compared to the times that it worked?

    The logs are unfortunately telling us much, Snapshot tries to use system backup for the process and if it fails it switches to PHP functionality which is slower and more resource heavy, so this just shows that system backups didn't work, but not happened further down the road.

    Could you also grant support access so we can have a closer look at this?
    To enable support access you can follow this guide here:

    Hi Seth,

    Looks like the issue is definitely due to system backups not being able to start at the certain time, so it uses PHP instead and that's more resource heavy.

    Can you try adding below code in your wp-config.php (located in main WP folder) just above the line:

    define('SNAPSHOT_FILESET_CHUNK_SIZE', 50);
    define('SNAPSHOT_TABLESET_CHUNK_SIZE', 250);

    This makes PHP backup to process smaller chunks at once and require less resources so when system backup fails hopefully this will be enough for the PHP backup to finish.

    It seems that your debug log is not attached above, can you try renaming it to .txt file and then upload again, so we can check if there's anything else in there.

    Best regards,
    Predrag

    Hi Seth,

    I'm afraid that there's still no file attached :slight_frown:
    Could you use any file sharing service like Dropbox or Google Drive, upload the file there and share the download link here?

    Also, did you apply the above mentioned changes to your site and did that made any difference?

    Best regards,
    Predrag

    ok sure thing

    I added the code

    I continue to get the error but managed snapshots says it is working - what is difference between requested system backup and "builtin"

    at this point we are about to go live and I will need a surefire backup system I look fwd to hearing back.

    Hi Seth,

    Thanks for that, I had a look at the logs but there's nothing in there that should be causing backup to fail, there are couple of warnings and rest are notices and all seem unrelated, there are no fatal errors that could give us some additional info.

    I continue to get the error but managed snapshots says it is working - what is difference between requested system backup and "builtin"

    Managed Backup tries to use System Backup, pretty much that's a backup performed by your server directly and this is a lot faster and less resource heavy, however some servers don't allow this so when it fails the plugin switches to builtin backup process.
    That builtin process is handled by PHP which is significantly slower and it doing this via PHP requires more server resources.
    So in your case, when the System Backup is blocked by your host, for some reason, it switches to PHP and your host most likely doesn't allow enough resources to allow it to finish.

    Could you provide us with cPanel or FTP login details so we can have a closer look at this?
    You can send us your details using our contact form https://premium.wpmudev.org/contact/#i-have-a-different-question and the template below:

      Hi Muted Industries,

      This issue is most likely related to server settings itself and usually require different tweaks to get it working.
      As explained above, the error you are seeing is telling us that system backup is unavailable so the plugin continues with PHP backup which requires more resources.

      Please start a new thread or chat and we will investigate this further for you.

      Best regards,

    Hi,

    we are experiencing the same issue.
    sites are backed up, but the logs get filled with the same warnings.

    In our case we have full control over the hosting server.

    Can you please tell us what to look for(what settings/modules should be switched on) or how to enable the "system backup"?

    kindest regards,
    Catalin

      Hi Catalin,

      This is actually not a issue, if you're backups are working there's really no need to change anything, this is just saying that one way of doing backups is not working and thus the plugin switches to alternative one.

      System Backup is usually something that host doesn't allow changing, but if you still wish to check it out these are the shell commands/binaries that have to be callable in order for the system backups to work: zip, ln, rm, mysqldump
      This is determined by calling -v <COMMAND> for each of them.
      As for the PHP requirements, it requires escapeshellarg, escapeshellcmd and exec - meaning, not disabled in your ini, or blacklisted via suhosin options.
      Additionally, it is checking for PHP safe_mode, which also has to be disabled.

      Best regards,
      Predrag

    Hi Predrag,

    It is an issue as it is resource heavy and it causing our nxginx to stop (surely its settings could be improved) but if there is a way to use "system backup" which takes less resource we would like to utilise that feature rather than the built one (fine for small sites, but not ideal for the bigger ones we have). I will pass the above to our devs. Should we need more support, I will be back :slight_smile: thank you. Catalin

Thank NAME, for their help.

Let NAME know exactly why they deserved these points.

Gift a custom amount of points.
