Rollback with YUM History Command
From 2daygeek.com Server patching is one of the important task of Linux system administrator to make the system more stable and better performance. All the vendors used to release security/vulnerabilities patches very often, the affected package must be updated in order to limit any potential security risks. Yum (Yellowdog Update Modified) is RPM Package Management utility for CentOS and Red Hat systems, Yum history command allows administrator to rollback the system to a previous state but due to some limitations, rollbacks do not work in all situations, or The yum command may simply do nothing, or it may remove packages you do not expect. I advise you to take a full system backup prior to performing any update/upgrade is always recommended, and yum history is NOT meant to replace systems backups. This will help you to restore the system to previous state at any point of time. n some cases, the hosted applications might not work properly or through some error due to recent patch updates (It could be some library incompatibility or package upgrade), what will be the solution in this case? Get in touch with App Dev team and figure it out an issue creating library' and packages then do the rollback with help of yum history command. ...

Very simply, you can use: backup.example.com# rsync -avz --numeric-ids --delete [email protected]:/path/ /backup/myserver/ To do the backup, you have to be root on the remote server, because some files are only root readable.

However, procrastination is a massive waste of time as it turns out. A survey in 2015 found that on average, a person loses over 55 days ...

Fixed drive letters for removable USB sticks
If you use multiple USB drives, you've probably noticed that the drive letter can be different each time you plug one in. If you'd like to assign a static letter to a drive that's the same every time you plug it in, read on. Windows assigns drive letters to whatever type of drive is available.
