backup php error

[Loreto]

Hi, when I try to make a backup, selecting "Resource Library Files" box, I get the next php error:

Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 1401857 bytes) in .../core/lib/targz.php on line 171

If I make the backup without Resource Library Files, everything is ok.

How can I fix the error?

Thank you.

There is it not enough memory in PHP set for full backup to be completed. You can increase this setting.

If you have access to your php.ini, increase the max memory size.

Or even in your .htaccess

php_value memory_limit 128M

Thank you, I'll try it
