I have the some issues on win7pro as UrB server.
That instance work more than 1 year, and about ~1 moths ago,
since that moment file backups shows me size -1 for most actual clients.
Copyes is not empty, I see it normal.
I have to delete all copyes after that moment, but new copyes also have “size -1”
I try to fing what goes wrong in database - file “backups” -
filter and delete all records with “size_bytes=-1” and their dir-s, the same resuts.
defrag_database, repair_database, remove_unknown (for mass-deleted dirs)
and upgrade 2.2.11 to 2.3.7 - changes nothing.
I have 1 theory - one of users downloads jpg file from internet to besktop,
that file has very long name, over the win7NTFS limits.
Windows allow to dowload it, but can not rename or delete them, may be there is relations?
Something goes wrong in write\move\map\hardlink\etc that file and database relations?
I have to delete it from NTFS by… 7zip arch with delete )
“too long path” and etc errors
