In original version all canvases were stored in a single JSON file. The

file would grow indefinitely. It would have to be stored in memory

whole. If it got corrupted, all canvases' data would be lost.

For all these reason now we store each canvas in its own file in

savedBoards/<whiteboard ID>.json

Each file is loaded only when corresponding canvas is used.

We can easily later do clean up - delete files which have not be used

for a year or so.

When doing a LAMS back up, the whole /savedBoards directory needs to be

backe up. Show less
