# Create a backup from a member of GR group , which at later point can be restored successfully.

|
|
# 0. Start GR on with 2 servers
|
|
# 1. Perform some DDL/DML operations on a member
|
|
# 2. Verify if the available backup (binlog file) can be later restored successfully on a non-member
|
|
# 3. Verify if that non-member can then be added to the GR group
|
|
# 4. Perform some DDL/DML operations to the group
|
|
# 5. Check mysqlbinlog output to test View Change Log events are written properly.
|
|
# 6. Cleanup
