VeeamON 2024 - Use Code "COMMUNITY10" for 10% Off!
In my interactions with numerous customers through my role, a recurring concern is their reluctance to grant open sudo access. However, many are more receptive to the idea of allowing limited sudo commands specifically needed by the application.Today, let's explore the sudo commands required by Veeam Backup & Replication v12 for the Veeam Agent for Linux. Bear in mind that this list is subject to modification based on community feedback. I encourage you to participate in this collaborative effort – feel free to suggest additions or removals to this list, which I've compiled based on my preliminary research.The necessary sudo commands for the veeamserviceraccount are as follows: veeamserveraccount ALL=/usr/bin/[ -d /tmp/ ],/usr/bin/id,/usr/bin/whoami,/usr/bin/mkdir,/usr/bin/rmdir,/usr/bin/arch,/usr/bin/uname,/opt/veeam/veeaminstaller,/usr/bin/rm,/usr/bin/cp,/usr/bin/chown,/usr/bin/veeamconfig,/usr/bin/chmod,/usr/bin/mv,/usr/bin/sh,/usr/bin/touch,/tmp/VeeamAgent*-*-*-*,/usr/bin/ps,/u
This blog provides the sizing calculations for the Veeam Plugin used with Oracle and SAP. It outlines the resource requirements on the Source Server, Veeam Repository Server, and Veeam Backup Server.Source Server Specifications:Resource Utilization per Channel:Each channel consumes 1 CPU and 200 MB of RAM.Calculation:# of Channels = CPU cores required.200 MB * Number of Channels = Total Memory Required.Veeam Repository Server Specifications:Resource Utilization:Every 5 channels require 1 CPU core and 1 GB of RAM.Veeam Backup Server Specifications:Resource Requirement:For every 1 million backup files, the server requires 15 GB of RAM.Dependency:The requirement is based on the number of backup files generated by Oracle and SAP. Example Calculation: Oracle Server Configuration: 12 Channels = 12 CPU Cores 200 MB * 12 = 2400 MB Memory Veeam Repository Server: 12 Channels / 5 = 2.4 CPU Cores 2.4 GB Memory Data Transfer Speed: Channel Capacity: Each channel transfers 120 – 150 MB/s, app
Restoring a database can often be a straightforward process, but complexities arise when you're working on the same server as the active original database. A common issue encountered in such scenarios involves the database's inability to start due to conflicts with BCT file access. This blog post is designed to guide you through resolving this issue when using Veeam Explorer for Oracle database restoration. Understanding the Problem:When you restore a database with a different name on the same server where the original database is still active, you might encounter an error where the newly restored database fails to start. This issue often stems from conflicts with accessing the BCT file. The BCT file, which is crucial for database operations, might still be in use or locked by the original database, leading to access conflicts. Step-by-Step Solution:To successfully restore your database without encountering the BCT file access issue, follow these steps: Step1: - Just restore(and not
Oracle Block Change Tracking (BCT) is a feature in Oracle databases that helps improve the performance of incremental backups by tracking the changes made to database blocks.When Block Change Tracking (BCT) is enabled, the database keeps track of all the blocks that have been modified since the last backup. This information is stored in a bitmap file, which is used by backup software to determine which blocks to backup. By only backing up the changed blocks, incremental backups can be performed more quickly and efficiently.BCT is particularly useful in environments with large databases or where backups need to be performed frequently. It can also be used in conjunction with other backup technologies, such as snapshot-based backups or replication.BCT can be enabled at the database or tablespace level and is compatible with both physical and logical backups. To enable BCT, the database must be running in ARCHIVELOG mode and the appropriate initialization parameters must be set. Oracle BC
One of the client recently requested me to help them find the duplicate bios uuid for their environment of 10K desktops, therefore, i am writing this post to help others if they are facing same issues with duplicate bios uuid.BIOS UUIDs are important identifiers that help distinguish one computer from another. They are typically unique, allowing administrators to manage their systems efficiently. However, in some cases, duplicate UUIDs might exist, causing confusion and possible errors. In this blog post, we'll show you how to create a PowerShell script that detects duplicate BIOS UUIDs on Windows computers and exports the results to an Excel file for further analysis.Step 1: Creating the PowerShell ScriptFirst, let's create a PowerShell script that queries a list of computers, retrieves their BIOS UUIDs, and checks for duplicates. You can get the list of computers from Active Directory, a text file, or an array.Here's a sample script that demonstrates these steps: # Import the Active
