Hello

Does it work with the previous version ? (1.6)

Best regards

Hello,

version 1.6 seems to work. I could start the backup and several transction points are already done.

In the actual log I found the entry
"13-02-28 19:56 - DETAIL - Plugin environment validated (OS, administrator rights and JRE architecture)", which I can't find in the log of version 1.7. Don't know if it's because of the different version or if it could be an useful information for you.
User #419 - 2013-02-28 20:18
Hi

This is because of a regression introduced in version 1.7.
It has been fixed in version 1.8

Best regards

Hi,

after deleting an unfinished Backup from version 1.6, version 1.8 is working.

Thanks for your quick help!
