Is the so-called strong twist of melon is not sweet, I think this is every webmaster know the truth. But in real life, regardless of you and me, we often make "strong twist melon" this mistake. For example, Baidu snapshots, many webmaster often tangled in their own site snapshot update is not diligent, or stagnation in a certain time.

Using Snapper in openSUSE for snapshot and rollback In the past, for a long period of time, we have to implement a file system snapshot in Linux to provide a feature for rollback. Now Snapper and Btrfs work together to fill this gap. Btrfs is a new Linux File System that copies data when writing data. It supports sub-volumes (one or more independent and mount file systems in each physical partition) file Sy

The KVM virtual machine defaults to the RAW format image format, the best performance, the fastest, its disadvantage is not support some new features, such as support image, zlib disk compression, AES encryption and so on.To use the mirroring feature, the disk format must be qcow2.

Of course, when the data is larger than a band, it is in the adjacent . Raid 4 is so, wafl cleverly uses it to optimize its performance. Raid dp (double In fact, they are similar to raid 6.
