Best practices: Cloud deployment considerations
Review the following considerations before you deploy cloud resources with NetBackup:
Virtual machine sizing
When selecting the virtual machine size follow the steps that are discussed in the chapters for sizing primary servers (Chapter 2) and media servers (Chapter 3). These recommendations also apply to deployments in the cloud.
NetBackup Installation
NetBackup installation options are available that use predefined systems in the cloud provider marketplace. Veritas provides these systems to the cloud vendors, and they include options for different NetBackup versions. Current customers may use their existing license key (BYOL); otherwise, contact Veritas Sales to request a key. If you chose to use another VM, then make sure that the installation disk is large enough for the NetBackup installation, with room for the NetBackup logs.
Operating systems
For NetBackup to operate optimally, you may need to change or tune various operating system settings, for example firewall settings, number of open files, and so on. Refer to the NetBackup Installation Guide for these recommendations.
Disk cache for cloud upload and download
The NetBackup cloud-tier allows each media server to create one or more cloud LSU. It is important to know that for each cloud LSU created, roughly 1 TB of MSDP pool is reserved for the LSU to be used as cloud disk cache. For a MSDP pool with limited storage size, the reserved disk cache can consume too much space, resulting in little usable space for regular backup jobs. If jobs are failing with error code 129 and 84, it may indicate that there is no space left on the device, even though the MSDP pool may still have plenty of available space according to df -h and dsstat. This is the default behavior. However, if the system has enough memory, and the useMemForUploadis set to true, the disk cache may not not be needed for upload. In this case, the CloudUploadCacheSize in
contentrouter.cfgcan be lowered to bypass the issue.
