GBase 8c 备份

GBase 8c 数据库支持备份功能

1.对集群每个cn和dn配置日志归档，命令如下：

gha_ctl configure wal_archive datanode hg_name dn_name 'ssh user@remote "flock -x path archive_wal dn_host dir/%p path %f"' -l dcslist -c cluster

gha_ctl configure wal_archive coordinator cn_name 'ssh user@remote "flock -x path archive_wal cn_host dir/%p path %f"' -l dcslist -c cluster

2.备份topo、dcs、gtm、cn、及各个高可用组：

命令:

gha_ctl backup xxx host path -l dcslist -c cluster

使用示例：

gha_ctl backup topo host path/topo.json -l dcslist  -c cluster

gha_ctl backup dcs host path -l dcslist  -c cluseter

gha_ctl backup gtm host path -l dcslist  -c cluseter

gha_ctl backup coordinator host path tbs_path -l dcslist -c cluster

gha_ctl backup datanode group host path tbs_path -l dcslist -c cluster
