When I restore the backup copy,Some errors occured!
My cluster has two nodes A、B
1、set some data into cluster
2、/opt/membase/bin/ep_engine/management/mbbackup /var/opt/membase/1.6.5/data/ns_1/default /var/backup/20110510/
3、echo 'flush_all' | nc 10.1.1.22 11211
4、/opt/membase/bin/ep_engine/management/mbrestore -a /var/opt/membase/1.6.5/data/ns_1/default /var/backup/20110510/default-*.mb
Some error occured:
The backup files need to be upgraded to version 2.
Either use dbupgrade or contact support.
What should I do?
