<p>Hi Angeliki,</p>
<p><br>
</p>
<p>I would normally advise against using EPrints for files larger
than 10GB, as the time to upload can be quite long and as they is
no in-built failure recovery, there is a higher chance that
uploads may fail and it will ultimately take longer to upload than
the same amount of data in smaller files. However, if the data is
being uploaded from fairly locally over a high bandwidth
connections you may be OK.</p>
<p><br>
</p>
<p>The Javascript that manages uploads can configured to limit the
max upload size but this is not the case by default. However, if
you check 88_uploadmethod_file.js and there is code like:</p>
<p><br>
</p>
<p>checkFilesize: function(file){<br>
if (file.size < max_size)<br>
{<br>
return 1;<br>
}<br>
eprints.currentRepository().phrase(
{'Plugin/Screen/EPrint/UploadMethod/<a class="moz-txt-link-freetext" href="File:filesize_too_big">File:filesize_too_big</a>':{}
},function(phrase){ alert (file.name+": \n"+
phrase["Plugin/Screen/EPrint/UploadMethod/<a class="moz-txt-link-freetext" href="File:filesize_too_big">File:filesize_too_big</a>"]);
} ) ;<br>
return 0;<br>
},<br>
</p>
<p><br>
</p>
<p>and max_size is set somewhere else in the script. Then you can
modify the value for max_size to allow for bigger files. If there
is no max_size set then you should be OK to upload any file size.
However, be sure to edit the right version of
88_uploadmethod_file.js as this can appear on lib/, site_lib/ and
archive level subdirectories. You want to edit the one at archive
level. If it does not exist copy the one from site_lib or if that
does not exist lib and then edit it at the archive level
(archives/ARCHIVE_NAME/cfg/static/javascript/auto/88_uploadmethod_file.js).</p>
<p><br>
</p>
<p>I don't know if web browsers have built in upload limits anymore
but if they do I would not be surprised if 10GB was a limit they
may have in place. So if you still cannot upload large files it
may be worth investigating if it is due to your web browser.
However, if the upload limit is not restricted by the setting of
max_size, I would not be surprised if the upload did fail at some
point because such a large file has more opporunity due to network
and other issues. There is also a small possibility that 10GB
leads to some integer overflow somewhere. It may be in the
Javascript in 88_uploadmethod_file.js but I am not aware of this
being an issue but I have not tried to upload files over 2-3GB.</p>
<p><br>
</p>
<p>Regards</p>

we have a limit on the uploaded datasets of 10 GB per
record. There are cases though, with much larger datasets
that have to be deposited in a single record. Would it be
possible to exceed this 10 GB limit? </p>
<p><br>
</p>
<p>Any recommendation will be very appreciated.</p>
