Support – Open source software can provide community support (such as mailing lists and forums) and professional support (such as distribution to provide additional paid support). You can use paid professional support to provide you with training and counseling.Reports and warnings – Finally, you must be able to see the backup report, the current working status, and also be able to provide a warning when a backup error occurs. bacula– A client serv
Before encountered the same problem, is the FD configuration file without errors, but is not backup, forget is God horse principle, anyway in hotsts file inside add a *.*.*.* bacula_storage on OK.Make a note first, it's a good head than a rotten pen!!!The reason here is that the address of the storage set in the Dir configuration file is a host name, not the IP address used, because there is no DNS or WINS resolution, so you can only use the hosts Dafa. This is the beginning to solve the problem

Difficulties in deployment of carrier SD-WAN, difficulties in sd-wan deployment
I. Introduction
Software defined wide area network (SD-WAN) is an important branch of software defined network (SDN). It is a hot field of SDN technology application. The main goal of SD-WAN is to achieve the network quality of leased line
Like most of my friends, I used to only use the SD card SPI mode. This mode is simple and can be implemented on most single-chip computers without the need for CRC verification. The SD mode can achieve simultaneous transmission of four data lines, which has a great advantage over the SPI mode in terms of speed. Therefore, this project selects the SD mode and uses
SD card If there is no problem, in general format can solve the problem. But make a good backup of your data. If the card itself has problems, it is not read out card. This is a good job, you can add other people's cards to try. If the identification, the phone is no problem, the problem is the card. Then back up the data, format the SD card, and then put back the phone. If the phone is still not read card,
Development Trend of SD-WAN in 2018, sd-wan in 2018
SD-WAN in 2017 has exceeded the industry's development expectations, has become one of the most popular trends in the network industry, each quarter survey agencies released the Forecast number is increasing, IDC predicts that the SD-WAN market will reach $8.05 billi
Debugging related to SD card is often encountered in andorid development, such as MP3 files and image files. When developing a simulator, you can simulate an SD card through a hard disk. The specific method is:
(1) Create an SD card image file: Open CMD and go to the tools directory of the SDK directory. Enter the following command: mksdcard64 m sdcard. IMG. This
