# 0.5.10 version broken!?

 * I usually check the newer versions of the plugins I install on my site on a local
   installation, but this time I just didn’t do it and I had a bit of a trouble!
   The 0.5.10 version of the plugin is either broken or something is not set properly
   for public release. I tried the new version on various installations and it is
   throwing the same error that something with my server is wrong. The backups are
   not created, only archives with the same name exists but they have O size. My
   server was constantly throwing errors about the limit of I/O operations, CPU 
   and memory use.
 * How I fixed it: disabled and fully removed the plugin, removed some leftovers
   manually and just copied the 0.5.8 to the plugins dir from previous backup, activated
   it through the admin panel and all is well – backups are created and restored
   successfully 3 times!!!
 * As the author advised in one of the other threads to get in touch with the hosting
   company, I did. What they confirmed is that the plugin is forcing the account/
   setup into high resource usage and the reason for server to respond with the 
   internal error is that. Of course that I suppose is normal, as a lot of people
   do not have unlimited resources hosting accounts!
 * As I said replacing the 0.5.10 version with the previous 0.5.8 works and it is
   compatible with WP 4.1 (at least for me).
 * Anyway, it is very good job done by the plugin author and I suppose it is something
   that will be looked at asap.
 * Happy New Year!

 * I too had this problem.
 * My host also said the problem was with the plugin. In my case I had just happened
   to make a package just before upgrading, used that with no issues.
 * I too think this plug in is awesome and have used it multiple times!

 * Hey design_studio,
 * Thanks for the feedback! Do you recall if you were using the database build mode‘
   PHP’ or ‘mysqldump’? New logic was added to this version which helps create an
   end of file marker in your SQL file, which requires the SQL file to be read into
   memory to write the marker. I think this may be causing the issue your seeing,
   but I need to know the DB mode as that will help me isolate the issue…

 * Hi there, thanks for answering so quickly. What is shown on the Scan page is 
   Build Mode: PHP (slow). What I’ve also found in the settings page is:
 * Database Build
    This server does not have shell_exec configured to run.
 * I am not sure if I must have this enabled, so I’ll get in touch with the hosting
   to discuss if I they can enable this feature. I suppose however for mysqldump
   to run.
 * Thanks.

 * OK Thanks… I’ll see if I can get out another version shortly to address the low
   memory bound settings… If you want to submit a support ticket I can have a deeper
   look at your setup. Right now its very difficult with some hosting companies 
   to work within such tight configuration constraints. Which means even the smallest
   features can break things on some servers…

 * Hey design_studio,
 * There is a new setting in the Developer version, under the Settings menu, its
   called Query Limit. This should help to conserve memory if you having memory 
   issues when using the PHP mode. Try and set this to it’s lowest setting if you
   have any memory issues. The very latest version (0.5.11) can be found by following
   these instructions:
 *  -> Browse to [http://wordpress.org/extend/plugins/duplicator/developers/](http://wordpress.org/extend/plugins/duplicator/developers/)
   -
   > Look for the section “Other Versions” -> Click on “Development Version” and
   download the zip plugin file -> Uninstall your current version and install this
   one
 * Let me know if this solves your issue…
 * Thanks

 * Hello and thank you for all your efforts. Unfortunately this version didn’t work
   as well. I tried all the options under the PHP settings and I receive one and
   same [error](http://i57.tinypic.com/2hpmvxx.png). I leave enough time between
   the tries to make sure the server is not pushed too much :). I can put the error
   log here if you want – I replaced the real paths for security reasons.
 * I am not an expert in anyway, but is there any chance something else to be the
   reason for the error. I still get the error for max I/O connections reached. 
   Do you think I have to ask the hosting to activate some option which might help?
 * I’ve just tried the 0.5.8 version and works like a charm.
 * Thanks again for all the efforts.
 * P.S. I’ve just made a [screenshot](https://wordpress.org/i57.tinypic.com/30wxg8z.png?output_format=md)
   of the resource page if you want to see how the resources are used when the plugin
   works. I can guarantee that there are no visitors or any other activities at 
   the same time. Taking another look to that screenshot myself it looks like 0.5.8
   maybe is using more resources than the last version. Then the error might be 
   somewhere else.
 * And of course this is the [completed](http://i62.tinypic.com/2n69iep.png) page(
   I removed the personal info from it).

 * That is interesting. That looks like an OS restriction setup by your hosting 
   provider. My feeling is that if your site gets much bigger then you will start
   to have issues on 0.5.8 as well, because the underlying logic that opens I/O 
   connections is almost identical. You may have to use the older version until 
   you reach an error on it. At that point you may have to create a directory filter
   on Step 1 of the package creation process to limit the amount of files it is 
   trying to archive.
 * If you want me to take a deeper look at your system you can submit a support 
   ticket and I’ll take a look at your server, and see if there is a way to get 
   around the hosts setup restrictions.
 * Hope that helps!

 * Hello again and thanks for your answer.
    Basically 3/4 of the archive size is
   wordpress files. the rest is mine. Which is like 3-5mb. Anyway, I’ll speak with
   them again as soon as I can and will see what the outcome will be.

 * Hi there,
    It took a while but here is the update.
 * My hosting were very kind and adjusted the amount of memory used (although this
   wasn’t a problem for all versions up to 0.5.8).
    I’ve seen that there is a new
   version out (0.5.12) so updated it.
 * It looks that the last 2 versions of the plugin use excessive amounts of memory
   and other resources (probably some limits must be set)! I don’t know if this 
   is result of the new logic you are talking but it just takes my shared hosting
   account to its knees.
 * Unfortunately something doesn’t work again and I get the same error in the front
   end. **However **the size of the final archive looks complete (and I have Build
   Start Build Finished message in the log), so I decided to give it a try and restore
   it locally in WAMP server.
    And everything looks great from the start to finish.
   With 0.5.10 and 0.5.11 versions the size of the archive was about half of the
   archive size now.
 * So locally restored all areas of the website works ok, however I am still not
   confident enough to do it on the real server and replace the working site. I 
   also noticed in the log that the plugin is unable to set the memory limit again.
   With kind of no restrictions on this on my hosting it looks like the plugin is
   not trying to set the limit (not sure if this is the case).
 * So finally as I said the archive works, but the front end throws an error. And
   I am sure it is not some kind of a timeout because the old 0.5.8 version takes
   almost double the time to complete, but there is a successful message and everything
   works with no problem.
 * The size of the site to backup is ~53MB. The archive is ~39MB. Basically this
   is 3/4 WordPress and few extra images.
 * Kind regards
 * P.S. I don’t want to sound ungrateful for the great job you are doing. I am just
   trying to help with that issue to be resolved if possible. But by no means you
   have to do that. Anyway. Thanks again

 * Hey Design_studio,
 * Its no problem… All input is helpful. There was new logic added in 0.5.10 that
   validates the SQL file was generated correctly, however it should not use up 
   too much memory. Something you might try if your having memory issues is to use
   mysqldump if its available. If not then you can try to keep the Query Limit really
   low. Both of these options are in the Settings menu.
 * If your still having issues feel free to submit a support ticket and I can have
   a look at your system if you want. If you decide to submit one, please refer 
   to this thread.
 * Cheers~
