Powershell Oracle Db Backup

Hi all,

I thought I would share with you this quick Powershell script I created to Export an oracle database, 7Zip it and then upload it to AmazonS3


param([String]$dumpname=(get-date -format dd-MM-yyyy))
Set-Alias sz "$env:ProgramFiles\7-Zip\7z.exe"
expdp <myDbUser>/<mypasswd>
   DIRECTORY=dmpdir DUMPFILE=$dumpname.dmp
sz a -mx "$dumpname.7z" "$dumpname.*"
Write-S3Object -bucket "company-ps"
   -profilename brian.keating
   -file "$dumpname.7z" -key "customer/dbdumps/$dumpname.7z"
remove-item "$dumpname.dmp"
remove-item "$dumpname.log"



How it works:

It uses the current date as the dumpname variable (unless specified as a parameter to the script)

It uses Oracle DbPump to export the database (assumes 7-Zip is installed in %\program files\)

It then writes the 7z file to AWS S3

Finally it removes the dump and log files.

AWS Powershell

ASW Powershell is installed on this server and I have already set a profile “brian.keating” with the following command.

set-awscredentials –AccessKey <ACCESSKEY> –SecretKey <KEY> -storeAs brian.keating



The server in this case is running in AWS, the 7zipped db is about 4Gb, and it uploads to S3 in about 30seconds (nice!)
