How to implement a script in Recovery Manager for AD to run after a backup is completed -
说明
This article explains how to implement a script in Recovery Manager for AD to run after a backup is completed. It's designed to allow RMAD to manage the retention of backups sent to the Additional Backup Path found on the Local Storage or Console Storage tab of a computer collection, for example:
-
原因
The controls at the bottom of the Local Storage tab only manage the retention of the Primary backup path. RMAD does NOT manage the retention of the Additional backup path. The additional path was developed so backups could be written to a file share collected by some other backup solution, in which case, that solution would then manage the retention of the backup. If this is not the case and would like RMAD to govern the retention, then you could use the script mentioned in the Resolution section below. -
解决办法
Local Storage Backup Flow
On the Local Storage (or Console Storage) tab, the Primary backup path must always be used. The backup file is first saved to the Primary backup path and then the RMAD server will copy it to the Additional backup path. If the backup fails to be saved on the Primary backup path, then it will never be copied to the Additional backup path.
We strongly recommend the Primary backup path always points to a local drive and folder on the RMAD server itself. For example "D:\RMADBackups". However, the Additional backup path is typically a UNC share (using CIFS or SMB), for example "\\<hostname>\RMADBackups".
If access to your UNC share is restricted by IP address, you only need to allow the IP of the RMAD server access to that share.
Another option: Use Remote Storage tab instead
Another option is to enter the share name in either of the paths (Primary or Additional) on the "Remote Storage" or "DC Storage" path:
Both the Primary and Additional Backup paths on this tab are managed by the settings at the bottom of the properties tab. Things to note when using Remote Storage:
1) The retention of both the primary and additional backup paths is governed by the same setting, so they are always the same.
2) The Backup agent on the Domain Controllers will copy the backup to both paths individually. Thus, if the Primary backup path fails, that does not affect the Additional backup path.
3) If access to the share is restricted by IP address (several enterprise backup solutions do this), then you need to allow access from the IP address of every DC you back up. This could be several IP addresses.
Because of the IP address restrictions some Enterprise backup solutions use, it may be better to use the Local Storage tab’s Additional backup path, and then run the script shared in this article.
Implementing the Script
The script is intended to be run from the "Advanced" tab of a computer collection, console side AFTER the backup creation is complete.
You must enter the same backup path ($backupPath variable), then the Script will delete any files that
(a) contain the DC name in the file name or path, and
(b) are older than the $nDays variable below.
The Delete_old_backups.ps1 script
Below is the script. Pay attention to the highlighted lines - you should either comment/uncomment or modify their values to meet your parameters.
Note: This script is not Quest-supported code. It has not gone through Quest's QA process and comes with no warranty, expressed or implied.
<# This script will find backups for computers in a computer collection on a UNC path,
then Delete those backups older than $nDays. It's intended to be run within an
RMAD computer collection to manage backups sent to the "additional backup path"
on the Local Storage tab. for RMAD versions 10.3.1 and earlier
Assumptions:
- Must be run on the RMAD server
- RMAD must be installed in its default location (C:\Program Files\Quest\...)
- Collection only contains DC Names (not containers, ADLDS servers or list files)
- Backup path must include %commputer% variable
