1.首先找到地址信息http://IP:端口/adminconsole/
这里替换成自己的地址http://localhost:8443/adminconsole/
选中Repository后，在Actions下选择Back Up Contents，按照界面提示进行备份。
2.使用pmrep命令备份，并可以结合计划任务，实现定时备份：
首先来看pmrep命令的相关帮助：
C:>pmrep help connect
Usage: pmrep connect
-r <repository_name>
{-d <domain_name>|
{-h <portal_host_name>
-o <portal_port_number>}}
[-n <repository_user_name>
[-x <repository_password>|
-X <repository_password_environment_variable>]]
[-t <client_resilience>]
help completed successfully.
C:>pmrep help backup
Usage: pmrep backup
-o <output_file_name>
[-d ]
[-f (overwrite existing output file)]
[-b (skip workflow and session logs)]
[-j (skip deploy group history)]
[-q (skip MX data)]
[-v (skip task statistics)]
help completed successfully.
使用pmrep命令备份的示例：
pmrep connect -r rep_name-d domain_name -n Administrator -x Administrator
pmrep backup -o E:backup_name.rep -f -b -j -q
