How to move large directory in source without duplicating backup?
If you move a file/folder in source BiT will treat it like a new file/folder and create a new backup file for it (not hard-linked to the old one). With large directories this can fill up your backup drive quite fast. You can avoid this by moving the file/folder in the last snapshot, too.
- create a new snapshot
- move the original folder
- manually move the same folder inside BiTs last snapshot in the same way you did with the original folder
- create a new snapshot
- remove the overlast snapshot (the one where you moved the folder manually) to avoid problems with permissions when you try to restore from that snapshot
