UCloud data Fangzhou evaluation report
UCloud data Fangzhou evaluation report
I. test environment:
One ucloud host CentOS6.5 2C4G
Ii. Test object:
Ucloud data Ark
Iii. Testing companies and departments:
Department I O & M Team (jiangchuan), cloud platform, R & D center, Guangzhou cloud Mobile Information Technology Co., Ltd)
Iv. Test content:
Data backup and recovery of Data Fangzhou
V. Test process and result:
1. The basic operations of Data Fangzhou were tested;
Create host (udata_test), creation time;
Click Backup management on the console, and you will find that the creation of a host completes full backup in seconds after initialization, no more than two minutes from the creation of the host;
Next, change the host name, and manually create a system disk to back up the manual backup, which takes about one minute;
Shut down the host and restore it to the first minute after the backup starts in seconds. After five minutes, the console displays that the backup was successfully restored;
However, after startup, a problem is found:
The root password is invalid! This indicates that there is a delay in the backup. The recovery time can only be postponed a little. After the recovery is successful, the system can be normally accessed. Then, use a manual backup to restore the system disk. The Restoration duration is about two minutes.
2. Simulate accidental deletion of data to verify the integrity after data recovery;
Insert several files of different sizes into the data disk (/data), and then delete all the data in the data disk;
Restore the data disk to the time point before data deletion;
The console is not displayed after the recovery is completed;
Refresh the console page to see that the recovery is successful;
Result All data on the data disk is completely restored;
3. test the impact of real-time data backup on performance and business;
To better test the data Ark, compile and install a lamp environment. During the compilation process, simulate compilation and installation errors and perform data rollback. The results are satisfactory, after the environment is set up, the wordpress product is deployed;
The simulated wordpress database (wp) is accidentally deleted;
After the data is restored, wordpress can be accessed normally without data loss;
In the actual use of wordpress, no exception occurs, and real-time access, write, and read operations are not affected.
Vi. Evaluation Summary
In today's especially important era of data, data is fundamental to most companies and the consequences of data loss are unimaginable. Therefore, data backup and disaster tolerance have become the top priority of every enterprise. The data ark of ucloud is a precedent for domestic cloud service providers to provide online continuous data protection!
The data Fangzhou test has indeed achieved the support provided by ucloud to restore the user to any second within 12 hours, any hour within the day, or any day within 3 days, this diverse backup mechanism greatly improves the user's disaster tolerance capability. At the same time, online real-time backup does not need to be stopped for read/write backup, which basically does not affect normal online services, it saves users' hard disk resources and reduces users' system overhead and costs. During restoration, the time is generally no more than 10 minutes, which also ensures quick recovery of user data; in general, the latest data ark of ucloud has grasped users' core needs, helped users continuously protect data, and solved users' data backup and recovery problems.
