###gitlab数据备份与恢复
1.查看组件状态
[root@gitlab ~]#gitlab-ctl status
run: alertmanager: (pid 38169) 1307s; run: log: (pid 38022) 1331s
run: gitaly: (pid 38196) 1305s; run: log: (pid 37306) 1434s
run: gitlab-exporter: (pid 38145) 1309s; run: log: (pid 37818) 1351s
run: gitlab-kas: (pid 38113) 1311s; run: log: (pid 37575) 1422s
run: gitlab-workhorse: (pid 38124) 1311s; run: log: (pid 37720) 1368s
run: logrotate: (pid 37223) 1448s; run: log: (pid 37255) 1445s
run: nginx: (pid 37748) 1364s; run: log: (pid 37759) 1363s

run: prometheus: (pid 38154) 1308s; run: log: (pid 37904) 1337s
run: puma: (pid 37653) 1382s; run: log: (pid 37660) 1381s
run: redis: (pid 37268) 1441s; run: log: (pid 37276) 1440s
run: redis-exporter: (pid 38147) 1309s; run: log: (pid 37835) 1345s
run: sidekiq: (pid 39364) 726s; run: log: (pid 37678) 1375s

2.备份
先创建一个project，如何执行备份操作
[root@gitlab ~]#/opt/gitlab/bin/gitlab-rake gitlab:backup:create

[root@gitlab ~]#ll /var/opt/gitlab/backups/1662111184_2022_09_02_15.3.2_gitlab_backup.tar -rw------- 1 git git 409600 Sep 2 17:33 /var/opt/gitlab/backups/1662111184_2022_09_02_15.3.2_gitlab_backup.tar

3.在创建一个project，执行恢复操作
[root@gitlab ~]#gitlab-ctl stop puma
[root@gitlab ~]#gitlab-ctl stop sidekiq
ok: down: sidekiq: 0s, normally up


[root@gitlab ~]#gitlab-rake gitlab:backup:restore BACKUP=1662111184_2022_09_02_15.3.2
#输入两次yes

[root@gitlab ~]#gitlab-ctl restart
ok: run: alertmanager: (pid 44752) 0s
ok: run: gitaly: (pid 44763) 0s
ok: run: gitlab-exporter: (pid 44778) 0s
ok: run: gitlab-kas: (pid 44780) 1s
ok: run: gitlab-workhorse: (pid 44792) 0s
ok: run: logrotate: (pid 44804) 1s
ok: run: nginx: (pid 44810) 0s
ok: run: node-exporter: (pid 44823) 1s
ok: run: postgres-exporter: (pid 44830) 0s
ok: run: postgresql: (pid 44916) 0s
ok: run: prometheus: (pid 44925) 1s
ok: run: puma: (pid 44937) 0s
ok: run: redis: (pid 44942) 1s
ok: run: redis-exporter: (pid 44948) 0s
ok: run: sidekiq: (pid 44955) 1s

#登录web界面查看，备份后新建的project没有了，恢复成功。
