You can backup and restore enabled databases and the text indexes that Text Extender has created.
To backup:
db2tx "GET STATUS"
db2tx "GET INDEX SETTINGS"
instance_owner_home_directory/db2tx/txins000 (UNIX) or DMBMMPATH\db2tx\txins000 (OS/2 and Windows NT)
Note that for partitioned databases, there are several instance directories, named txins000, txins001, ..., so it would be more convenient to backup the whole .../db2tx directory rather than the files in the individual directories.
TXSTART
To restore:
TXSTOP
