Writes are buffered (cached) in memory, and written to the storage device at the optimal time. The sync command forces an immediate write of all cached data to disk.Run sync if you anticipate the system to be unstable, or the storage device to become suddenly unavailable, and you want ...

基于boost1.43.0,inotify api,rsync command.开发。目前使用的比较多的同步解决方案是inotify-tools+rsync ,另外一个是google开源项目Openduckbill(依赖于inotify- tools),这两个都是基于脚本语言编写的。相比较上面两个项目,本项目优点是: sersync是使用c++编写,而且对linux系统文件系统产生的临时文件和重复的文件操作...

you can use DPM, Windows Server Backup (WSB), or the diskshadow command to easily backup and restore Hyper-V virtual machines INCLUDING Linux! One challenge with Linux had been the lost seconds on in the Linux VM clock when the VM is “frozen” for backup (not an issue for most ...
To confirm ntpd is synchronizing correctly, run thentpq -pcommand. Some Azure Marketplace images with Linux are being changed to use chronyd as the time sync service, and chronyd is configured to synchronize against the Azure host rather than an external NTP time source. The Azure host time...
