标签：sys 备库 log -- 备份 kingbase repo home backup
案例说明：
此案例是在KingbaseES V8R6集群环境下，当主库磁盘空间不足时，执行sys_rman备份，将集群的备库节点作为repo主机，执行备份，并将备份存储在备库的磁盘空间。
集群架构状态：
[kingbase@node102 bin]$ ./repmgr cluster show
ID | Name | Role | Status | Upstream | Location | Priority | Timeline | Connection string
----+---------+---------+-----------+----------+----------+----------+----------+----------------------------------------------------------------------------------------------------------------------------------------------------
1 | node101 | primary | * running | | default | 100 | 3 | host=192.168.1.101 user=system dbname=esrep port=54321 connect_timeout=10 keepalives=1 keepalives_idle=10 keepalives_interval=1 keepalives_count=3
2 | node102 | standby | running | node101 | default | 100 | 3 | host=192.168.1.102 user=system dbname=esrep port=54321 connect_timeout=10 keepalives=1 keepalives_idle=10 keepalives_interval=1 keepalives_count=3
主机节点信息：
适用版本：
KingbaseES V8R6
一、在repo主机配置sys_backup.conf
[kingbase@node102 bin]$ cat sys_backup.conf |grep -v ^$|grep -v ^#
_target_db_style="cluster"
_one_db_ip="192.168.1.101"
_repo_ip="192.168.1.102"
_stanza_name="kingbase"
_os_user_name="kingbase"
_repo_path="/home/kingbase/kbbr2_repo"
_repo_retention_full_count=5
_crond_full_days=7
_crond_diff_days=0
_crond_incr_days=1
_crond_full_hour=2
_crond_diff_hour=3
_crond_incr_hour=4
_band_width=0
_os_ip_cmd="/sbin/ip"
_os_rm_cmd="/bin/rm"
_os_sed_cmd="/bin/sed"
_os_grep_cmd="/bin/grep"
_single_data_dir="/home/kingbase/cluster/R6HA/kha/kingbase/data"
_single_bin_dir="/home/kingbase/cluster/R6HA/kha/kingbase/bin"
_single_db_user="system"
_single_db_port="54321"
_use_scmd=on
二、在repo主机执行初始化
[kingbase@node102 bin]$ ./sys_backup.sh init
# generate local sys_rman.conf...DONE
# update all node: sys_rman.conf and archive_command with sys_rman.archive-push...
# update all node: sys_rman.conf and archive_command with sys_rman.archive-push...DONE
# create stanza and check...(maybe 60+ seconds)
# create stanza and check...DONE
# initial first full backup...(maybe several minutes)
# initial first full backup...DONE
# Initial sys_rman OK.
'sys_backup.sh start' should be executed when need back-rest feature.
'sys_backup.sh start' will add CRONTAB items.
Or you can manual backup once with user-guide.
三、查看主备库sys_rman配置文件
# 备库（repo主机）
[kingbase@node102 bin]$ cat /home/kingbase/kbbr2_repo/sys_rman.conf
# Genarate by script at 20220714154403, should not change manually
[kingbase]

kb2-host-user=kingbase
[global]

repo1-retention-full=5
log-path=/home/kingbase/cluster/R6HA/kha/kingbase/log
log-level-file=info

# 主库：
[kingbase@node101 bin]$ cd ~/kbbr2_repo/
[kingbase@node101 kbbr2_repo]$ cat sys_rman.conf
# Genarate by script at 20220714154413, should not change manually
[kingbase]
kb1-path=/home/kingbase/cluster/R6HA/kha/kingbase/data
[global]
repo1-host=192.168.1.102
repo1-host-user=kingbase

log-level-file=info
log-level-console=info
log-subprocess=y
band-width=0
cmd-ssh=/home/kingbase/cluster/R6HA/kha/kingbase/bin/sys_securecmd
四、创建备份执行计划
[kingbase@node102 bin]$ ./sys_backup.sh start
Enable some sys_rman in crontab-daemon
Set full-backup in 7 days
Set incr-backup in 1 days
0 2 */7 * * kingbase /home/kingbase/cluster/R6HA/kha/kingbase/bin/sys_rman --config=/home/kingbase/kbbr2_repo/sys_rman.conf --stanza=kingbase --archive-copy --type=full backup >> /home/kingbase/cluster/R6HA/kha/kingbase/log/sys_rman_backup_full.log 2>&1
0 4 */1 * * kingbase /home/kingbase/cluster/R6HA/kha/kingbase/bin/sys_rman --config=/home/kingbase/kbbr2_repo/sys_rman.conf --stanza=kingbase --archive-copy --type=incr backup >> /home/kingbase/cluster/R6HA/kha/kingbase/log/sys_rman_backup_incr.log 2>&1
五、备份测试
