Veeam 7 was released recently. First, we will introduce seven functions of Veeam 7.

Recently installed a Veeam server, you need to restore some file server information, but the implementation of the task of the following error occurred650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M02/3E/58/wKiom1PHQqOSDTh1AAFT6Q3u6hs815.png "title=" error. PNG "alt=" Wkiom1phqqosdth1aaft6q3u6hs815.png "/>After some research, it is found that this problem is caused by the use of data deduplication on the file server.There are two workarounds,
Two ways to back up Veeam
Veeam creates two backup files, VBK is a full backup, and Vrb/vib is an incremental backup file used to record changes.Reversed Incremental BackupEach incremental backup updates the VBK file, and VBK is the latest full backup, restoring the latest backup as long as the VBK is restored. The modified content in VBK is saved to VRB in each incremental backup, so it is called REVERSED
Veeam backup Replication 9.5 permanent hack activates VMware Hyper-V BackupVeeam Backup Replication is a powerful, easy-to-use, cost-effective backup and availability solution that enables fast, flexible, and reliable recovery of virtualized applications and data, consolidating virtual machine (VM) backup and replication capabilities into a single software solution. Veeam Backup Replication provides award
Beans are usually used to monitor the state of the system with Nagios. The usual company uses Veeam to manage backup and restore of files, and the results of backups are usually sent to beans via email. On a whim today, I want to show the status of this backup in Nagios's monitoring interface.Because Veeam itself provides modules for PowerShell, beans can invoke custom PowerShell scripts through the nsclien
Veeam Backup Replication synchronization is different from the mechanism of backup, synchronization is to crawl the virtual machine directly to the other end, the equivalent of a full standby, and then according to the scheduled task to take a snapshot, and based on the configuration to retain the most recent snapshots for failover recovery, This example synchronizes from a 61ESXi host to a 70ESXi host.1. Add a sync taskTwo ESXi hosts, synchronizing
1. disable all INPUTFORWARDOUTPUT to open only some ports. The following is the command implementation: iptables-PINPUTDROPiptables-PFORWARDDROPiptables-POUTPUTDROP and then use the command iptables-L-n to check whether the settings are correct. you can see that all the settings have been dropped.
1. disable all input forward output and only open it to some ports.The following is a command implementation:

Click iptables-L-n to check whether it has been cleared.5. Filter invalid data packetsAssume that someone enters the server or has a virus Trojan program, it can transmit data outside the server through port.This method is different from the normal access to port 22 and 80. The data it sends to the external server is not sent by visiting the webpage.The response packet.
We will disable all the packets that are not responded through the request a
The SELinux security control of Linux is used for ports in addition to the file system, which enables processes that are started as services to be monitored only on a specified number of ports. For the narrative convenience we call the controlled port.Nginx Monitor PortTo see which managed ports are currently executable:grep ' ^http_port_t ' http_port_t
CentOS commands for viewing IP addresses, modifying IP addresses on ports, and activating ports
You know, you get used to ipconfig in windows, and it is a lot of trouble to view IP addresses in CentOS;
The information collected today focuses on IP port problems:
View IPIfconfig eth0 → view the IP address, but the output information is moreIfconfig | grep 'bcast' → the output information should be much cle

Sometimes we have Tomcat installed on the service Linux server (port number 8080), and the company's requirement is to enter the URL without adding a port number to access it, which means that the browser has to access your Tomcat (port 8080) via port 80, for which there are two solutions:
1. The Linux system prohibits 10,241 ports from being used by non-root users, then you must log on with root to start Tomcat modified to port 80 (note: directly in
