ISSUE: https://github.com/FirebirdSQL/firebird/issues/7186
|
|
TITLE: Nbackup RDB$BACKUP_HISTORY cleanup
|
|
DESCRIPTION:
|
|
Test verifies ability to specify command switches '-clean_history' and 'keep N rows' in NBACKUP utility.
|
|
Temporary user and role are created. System privilege USE_NBACKUP_UTILITY is granted to role, and role is granted to this user.
|
|
All executions of NBACKUP are performed as this temporary user.
|
|
|
|
Several levels of incremental backups are created WITHOUT this command switches (see 'NBK_COUNT_BEFORE_CLEANUP').
|
|
Then we run nbackup <NBK_COUNT_WITH_CLEANUP> times with switch '-clean_hist' and require to keep <NBK_KEEP_ROWS> rows.
|
|
Finally, we check content of RDB$BACKUP_HISTORY table: only NBK_KEEP_ROWS records must be selected from it.
|
|
|
|
::: NB :::
|
|
It seems that currently firebird-driver does not support Services API parameters related to cleanup history
|
|
(isc_spb_nbk_clean_history; isc_spb_nbk_keep_days <int> and isc_spb_nbk_keep_rows <int>).
|
|
Test will be modified after introducing this supoport.
|
|
|
|
Checked on 5.0.0.967 SS/CS, 4.0.3.2904 SS/CS -- all fine.
