Description

File names of flvRecordings and fileExplorerItem::Video are depends on id
this might cause file damage after import/export

steps:
1) create 5 recordings ( id == 1 ...5 )
2) delete recordings with id = 2 and 3
3) perform export/import
NOTE: max id in DB is now 3
4) create recording
Result: previous file will be rewritten, to recordings will have same fileset

I believe we should switch to UUID as hash (during backup import) and use if for all future recordings/video uploads
