How many times a snapshot is made is customized, such as it can be done every 4 hours.For example there are a,b,c,d of four files.1) First Snapshot (COW):The snapshot is instantaneous, when the camera creates a snapshot space, for example, 20%, then changes the a file to A1 (the change is compared to the time of the photo), Checkpoint/snap shot is a file, and then back up the CK. Restore the words according to CK's pointer (pointing to the source file) +ck file (a file before the change) to reco

Duplicate data deletion (De-duplication, DDD) is one of the advanced features of networked storage devices, which can effectively reduce the storage space occupied by duplicate data and increase the space utilization of storage devices. The data de-duplication feature for NetApp filer is called a-sis. When applying the command line in the following example, replace the/vol/vol1 with your own volume name.

Starting with 2.6.13-RC3, the Linux kernel provides the ability to dynamically bind and Unbind devices and device drivers in user space. Prior to this, the insmod can only be bound and reconciled through the modprobe and rmmod, and this binding and bundling is for the driver and all devices. The new feature can set the connection between the driver and the individual device.Here, we take the NVMe SSD for PCI bus as an example, first execute LSPCI disp

Without knowing it, cloud computing has been around for so many years. For the cloud, people are excited from the beginning of their contact with each other, continue to debate, and then fight for public cloud, private cloud, and hybrid cloud, now it's time to pull the cloud and witness "turning the cloud into rain. From the blind pursuit of the cloud at the beginning to the present, users began to become rational. If they could bring direct benefits, they would be useless. Based on different a
