Move BACKUP_DIR to /tmp

[okraits]

BACKUP_DIR doesn't contain configuration files but runtime data and thus
should live in /tmp.

I can not change the backup dir to /tmp. Since I want to keep backup file after the router reboot. And saving the backup in tmp will cause the loose of the backup file after the reboot

Maybe it is possible to make it configurable?
The Problem is that if "easycwmp" is running on a device with NAND-flash that on every write to the backup directory a whole erase block of the NAND must be rewritten. I dont know exactly but the backup.xml is written on every INFORM?

Yes, the backup is writen in every inform.
May be your idea is good. make the backup file path configurable.
Could you open a ticket about that in support.easycwmp.org
