I need a solution
I have a problem with DLO and Thunderbird (https://www.mozilla.org/en-US/thunderbird/). Thunderbird saves messages to files which have no extension. When DLO wants to back up such file it starts "Calculating Delta". During this task Thunderbird can't write to the file and the "Calculating Delta" takes too long if the files are large (e.g. ~ 1GB). If the problem occurs then a user has to suspend DLO Agent for a while and Thunderbird can write new data to its files. Then the user has to resume DLO Agent. It means in this case a combination of DLO and Thunderbird is useless.
Is there any possibility how to avoid above problems?
