using xcopy to backup files

Use Ghost to make the partition image file, and then overwrite the image file on the original partition when recovering. In many people's view, the use of Ghost backup and restore files is a very dangerous operation, a little attention will result in an "innocent" section of the file is overwritten, causing irreparable damage. In fact, you can quickly and securely back up and restore your system as long as

you do not want to expand into multithreaded form, reference to the first write traversal function (show_structure) directly to the file will be called the Windows API (described later) for replication, do not need to talk about the file path to be backed up to save.If you want to consider multithreaded extensions, we need to take a long-term view.For a backup model, the best thing to do is to use a queue, still implement traversal mode, but save the

MySQL database backup tools are many, but here is a small and easy to use the Mysqldump tool, located in the database directory Bin/mysqldump.exe. These days with phpMyAdmin back up the database when there are garbled, Repeated in the local and remote DreamHost space to test the database, but still export the database will appear garbled, should be the problem of phpMyAdmin, the database itself is not a problem. Pull away, hehe. I google about the Mys

of MySQL Relay log: From the error point of view, meaning is to start slave, the use of repository information initialized Relay log structure failed. Why did it fail? The localhost-relay-bin.000001 file was originally not found in the Mysql-relay-bin.index file. Here, the answer is very clear, because I use a cold backup file recovery instance, in the MySQL library in the Slave_relay_log_info table still retains the previous relay_log information, s

In oracle 9i, you can easily export data as files or import data from files. The oracle management server (oms) can be easily implemented. There are many instructions to explain throughout the operation, but there are not many complete guidance materials. There are many so-called masters on major forums. The answer to this topic is often that the experts do not use oms, so use exp/impl. If you insist on ask

First, cold backup1, cold backup occurs when the database has been shut down normally, before making a cold backup, you usually need to know the name of the backup file and the path Copy Code code as follows: Sql>select name from V$datefile; Sql>select name from V$controlfile; Sql>select member from V$logfile; 2, cold

In actual use, we encountered a problem. In Android, the browser does not recognize multi-CN domain names, "The certificate name does not match the server name" will be reported.

have heard another saying that this approach takes full advantage of the results of mathematics, not the simple logic that I use:http://librsync.sourcefrog.net/This means that after the first upload, the file will never change, and each time the local file is modified, the difference between it and the first file can be calculated. This way, no matter how many times the file is modified, it will always be a raw file and an incremental file, and it will be able to generate new

I have paid a lot of effort to improve it ........ You only need to define the following basic variables in the batch processing to generate clone instances of any Sid to any directory.

mysql| Backup | recovery | Data database destruction occurs for a number of reasons and varies from one degree to the other. If you're lucky, it could be a small damage to one or two tables (for example, if your machine is temporarily shut down due to a power outage). If this is not the case, you may need to replace the entire data directory (for example, if a disk is paralyzed and the data directory is on it). In other cases, recovery operations are
