NetApp SnapCenter
From the ‘NetApp Data Broker 1.0.1 Data Protection
Guide for VMs, Datastores, and VMDKs using the SnapCenter Plug-in for VMware
vSphere’
Prerequisites for restoring guest files and folders:
Before you restore one or more files or folders from a
VMDK on a Windows guest OS, you must be aware of all the requirements.
1) VMware Tools must be installed and running. SnapCenter
uses information from VMware Tools to establish a connection to the VMware
Guest OS.
2) The Windows Guest OS must be running Windows Server
2008 R2 or later.
3) The credentials for the target VM must specify the
built-in domain administrator account or the built-in local administrator
account. The username must be "Administrator." Before starting the
restore operation, the credentials must be configured for the VM to which you want
to attach the virtual disk. The credentials are required for both the attach
operation and the subsequent restore operation. Workgroup users can use the
built-in local administrator account. Attention: If you
must use an account that is not the built-in administrator account, but has
administrative privileges within the VM, you must disable UAC on the guest VM.
NetApp SnapCenter 4.3
Dec 12, 2019: NetApp SnapCenter Released
- Simplified SnapCenter High Availability (HA) Support:
SnapCenter can now work with external hardware load
balancer f5 to provide HA capability in an active/passive mode configuration.
With few simple cmdlets one can setup MySQL replication and enable HA for
SnapCenter server.
- Concurrent upgrades of hosts:
You can now select multiple hosts and perform parallel
upgrades of the hosts irrespective of the plugin type.

News
Oracle
Oracle have provided many performance gathering and
reporting tools over the years. Originally the UTLBSTAT/UTLESTAT scripts were
used to monitor performance metrics. Oracle 8i introduced the Statspack
functionality which Oracle 9i extended. In Oracle 10g statspack has evolved
into the Automatic Workload Repository (AWR).
Note: This functionality requires Enterprise Edition
and the Diagnostics and Tuning option.
Security
Unlike most ransomware strains, the Snatch ransomware
also steals files from infected networks.
Cyber-security firm Emsisoft said it found a bug in
Ryuk's decrypter app that makes
file recovery impossible, even after paying the ransom demand.
OpenVPN, WireGuard, and IKEv2/IPSec VPNs are
vulnerable to attacks!
Veeam
A Veeam product I wasn’t aware of:
“Well after months of trying to get this worked out, I
finally got Synology support to remote in and take a look. They were awesome
and after combing through logs and wireshark files, they finally were able to
change the setting "Do not reserve disk space when creating files" to
checked instead of unchecked and it INSTANTLY increased my speed from 3MB/s to
over 60 MB/s (90MB/s+ at some points).”
