# TEST backup
|
|
# TEST Test of hotbackup functionality.
|
|
# TEST
|
|
# TEST Do all the of the following tests with and without
|
|
# TEST the -c (checkpoint) option; and with and without the
|
|
# TEST transactional bulk loading optimization. Make sure
|
|
# TEST that -c and -d (data_dir) are not allowed together.
|
|
# TEST
|
|
# TEST (1) Test that plain and simple hotbackup works.
|
|
# TEST (2) Test with -data_dir (-d).
|
|
# TEST (3) Test updating an existing hot backup (-u).
|
|
# TEST (4) Test with absolute path.
|
|
# TEST (5) Test with DB_CONFIG (-D), setting log_dir (-l)
|
|
# TEST and data_dir (-d).
|
|
# TEST (6) DB_CONFIG and update.
|
|
# TEST (7) Repeat hot backup (non-update) with DB_CONFIG and
|
|
# TEST existing directories.
