Yes
My strategy is:
Level 0 once.
Increment level continuously every third Day.

Works fine most of the times. Sometimes I get mysteriously the following error even though my logs tell that the order is right. I suspect there might be an old bug in NBAK in version i'm using 2.5.3.26778

Invalid level 6 of incremental backup file: /home/firebird/store_fdb/2058/unzip_nbak/N0006_201807
29_1000.nbk, expected 1 [SQLState:HY000, ISC error code:335544382]

When this happen I just step back one level.

NBAK backup is done with Jaybird.

It would be really cool if N backups can be reused when we migrate to FB4.
