Description
Technical field
The invention belongs to multi-node incremental backup technical field, more particularly to a kind of multinode Fast incremental backup side
Method.
Background technology
Incremental backup refer to a full backup or on once after incremental backup, later each backup is only backed up with before
Once compared to the file for increasing or being changed.It is produced afterwards it means that the object of first time incremental backup is that progress is entirely standby
Raw increase and the file of modification；The object of second of incremental backup be carry out first time incremental backup after it is generated increase and
The file of modification, and so on.This most significant advantage of backup mode is exactly：The Backup Data not repeated, therefore back up
Data volume it is little, it is very short to back up the required time.But the data recovery of incremental backup is cumbersome.You must have upper
Full backup and all incremental backup tapes (once losing or damaging magnetic tape reel therein, will result in the mistake of recovery
Lose), and they must push away recovery along from full backup to the time sequencing of incremental backup successively is counter one by one, therefore this is with regard to very big
Ground extends recovery time.
Backup rate is advantageous in that using incremental backup is maximum：Its speed upper many faster than full backup, while by
In incremental backup, whether meeting automatic decision BACKUP TIME point and file have been changed before backuping, so compared with complete backup
It is also very beneficial for saving memory space.
Service system is frequently with multiserver node, and it is standby to be commonly encountered data for the incremental backup of data in multiserver node
Part is inconsistent to cause the problem of data backup is chaotic, incremental backup efficiency is slow, this invention address that invention one kind ensures that data are standby
Part accuracy, synchronism while improve incremental backup efficiency.
