Backup/restore Principles for SQL Server differential backupsRemember one point: Differential backups are based on the difference from the last full backup, not the difference based on the last differenceBackup process:1-After a full backup there have been no modifications to the database, if any, the last LSN of the logging database if no changes have been made to the database after the full backup, then the differential backup is meaningless 2- Read

Oracle user-managed backups introduces how to manage backups. the following concepts are described: Full-Database Backup: 1. consistent backup (cold backup), that is, backup after the database is closed, because the data file header and the control file SCN are the same because redo has been applied, therefore, you only need to back up data files and control files. Of course, you can also back up log files

Books, photos, movies: More and more data are being digitized; hard-disk makers are constantly improving their technology to make hard drives cheaper-and now the PC capacity is calculated by T. Increasing storage space and a wide variety of data sources make data backup a necessary step in system maintenance--once a hard drive fails, the damage is much greater than the price of the hard disk. Fortunately, OS X built-in "Time Machine" function, it can make the backup system a very simple operatio

While the backup database is usually in the early hours of the basic no database operation, so we can not ask the administrator every day to the night 1 o'clock to back up the database. The most common way to implement scheduled automatic backups of a database is to use jobs in SQ

As we all know, the drivers on the computer, like other files on the system, can be compromised and run out of control, perhaps to reinstall or upgrade the driver. In daily life, before we reinstall the operating system, we may not be able to find a NIC or modem driver, fearing that the network device could not be installed. Now it's easy, and Windows tuning Guru provides the ability to drive smart backups. Here, let's look at how Windows Optimizer Ma

Open the SQL Server Agent serviceTo implement the automatic backup feature, first make sure that SQL Server's SQL Server (proxy) service is turned on.If you do not see this SQL Server Agent node, you can open it in the following wayFind "Microsoft SQL Server R2" in the Start menu and select "SQL Server Configuration Man

There is a need to back up the data from the production library to the backup machine at 23 o'clock every night, the database of the backup machine can be used directly the next day, the data is the data of the production library yesterday. (production data is not much, all data is not more than 3000w).With no exposure to advanced Oracle knowledge, only simple IMPDP and EXPDP tools are available, so it is intended to be done with this self-brought command and shell script.Now assume that the pro

prevents SQL Server from rolling back (redo and undo) and recovering the action?In fact, in the real bad situation, most of this problem is caused by a hardware error, but this kind of error is often permanent with the contents of the bad backup file, before SQL 2005 version, encountered this problem can only go to find an earlier backup. But that means there's a lot of data loss to be generated.So after SQL 2005 introduced a new "Ignore error" recovery function, this situation in distress is a

Cold backup is a statement that copies critical files to another location. The fastest and safest method for backing up Oracle information for cold backups. The advantages of cold backup are: 　　 1, is very fast backup method (just copy files)2,

I personally think this model is very nice, sometimes the index of a document may produce a large index file, will be very much bandwidth, and only transfer the original file is much better.When the query is, if the
