将应用程序快照备份到计算机

此方案说明如何自动将日常服务维护过程中创建的快照备份到本地计算机。

下载在维护期间创建的应用程序快照 (Artifact Snapshot)
通过附加时间戳重命名下载的快照
如果需要，通过删除最早的备份保留 10 个备份

Note:

此脚本不能用于备份 Narrative Reporting
如果将该脚本改作他用，请根据需要修改运行时参数（url、user、password 和 NumberOfBackups）的值。

有关使用 Windows 任务计划程序计划脚本的信息，请参阅“自动执行脚本”。

Windows 示例脚本

创建包含类似以下脚本的批处理 (.bat) 或 shell (.sh) 文件以自动下载快照。

@echo off
rem Sample script to download and maintain 10 maintenance backups
rem Update the following  parameters

SET url=https://example.oraclecloud.com
SET user=ServiceAdmin
SET password=Example.epw
SET SnapshotName="Artifact Snapshot"
SET NumberOfBackups=10

rem EPM Automate commands
call epmautomate login %user% %password% %url% 
     IF %ERRORLEVEL% NEQ 0 goto :ERROR
       call epmautomate downloadfile %SnapshotName%
     IF %ERRORLEVEL% NEQ 0 goto :ERROR
       call epmautomate logout
     IF %ERRORLEVEL% NEQ 0 goto :ERROR

rem Rename downloaded Artifact Snapshot, keep the last 10 backups
Set Timestamp=%date:~4,2%_%date:~7,2%_%date:~10,2%%
Set Second=%time:~0,2%%time:~3,2%
ren %SnapshotName%.zip %SnapshotName%_%Timestamp%_%Second%.zip

SET Count=0
FOR %%A IN (%SnapshotName%*.*) DO SET /A Count += 1
IF %Count% gtr %NumberOfBackups% FOR %%A IN (%SnapshotName%*.*) DO del "%%A" && GOTO EOF
:EOF

echo Scheduled Task Completed successfully
exit /b %errorlevel%
:ERROR
echo Failed with error #%errorlevel%.
exit /b %errorlevel%

Linux/UNIX 示例脚本

创建一个 shell (.sh) 文件，在其中包含类似如下所示的脚本，以自动下载快照。如果密码中包含特殊字符，请参阅“处理特殊字符”。

#!/bin/sh
# Sample script to download and maintain 10 maintenance backups
# Update the following seven parameters

url=https://example.oraclecloud.com
user=serviceAdmin
password=/home/user1/epmautomate/bin/example.epw
snapshotname="Artifact Snapshot"
numberofbackups=10
epmautomatescript=/home/user1/epmautomate/bin/epmautomate.sh
javahome=/home/user1/jdk1.8.0_191/

export JAVA_HOME=${javahome}

printResult()
    {
    op="$1"
    opoutput="$2"
    returncode="$3"

    if [ "${returncode}" -ne 0 ]
    then
        echo "Command failed. Error code: ${returncode}. ${opoutput}"
    else 
        echo "${opoutput}"
    fi
}

processCommand()
{
    op="$1"
    date=`date`

    echo "Running ${epmautomatescript} ${op}"
    operationoutput=`eval "$epmautomatescript $op"`
    printResult "$op" "$operationoutput" "$?"
}

op="login ${user} ${password} ${url}"
processCommand "${op}"

op="downloadfile \"${snapshotname}\""
processCommand "${op}"

op="logout"
processCommand "${op}"

# Renames the downloaded artifacts, keeps the last 10 backups
timestamp=`date +%m_%d_%Y_%I%M`
mv "${snapshotname}.zip" "${snapshotname}_${timestamp}.zip"

((numberofbackups+=1))
ls -tp ${snapshotname}*.zip | grep -v '/$' | tail -n +${numberofbackups} | xargs -d '\n' -r rm --
