pc companion safety copy does not work

[Stenbocken]

Tried making a safety copy on my xperia z2 with pc companion but I cant even start creating a copy. Pc companion starts investigating filesystem after 20 minutes I gave up, twice. No error messages no nothing...

It might be related to a large amount of data.How much data did you try to backup?

About 10 gb.

That is a huge backup file.Normally,you have to backup only contacts,messages,account datas etc.Leave media files out and copy them manually.
