Shadow Copies0:12 – Shadow Copies was first introduced in Windows XP.. It works by creating a snapshot of the drive sầu. The main aim was to lớn allow backup software like NT Backup to lớn be able lớn backup open files. The initial release of Shadow Copies only allowed for a temporary snap shot for the purpose of backing up the files. Later versions of Windows allow files to be restored from the snapshot. However, Shadow Copies should not be considered a replacement for regular backups. This is because snapshot records can & will change. If a file has not changed, the file is not included in the snapshot. If the user were to later delete a file that were not in the Shadow Copy storage, the only way khổng lồ recover the tệp tin is to restore the tệp tin from the regular backup. Snapshots also operate under space restrictions imposed by the amount allocated khổng lồ them & the number of snapshots that have sầu already been created. When a storage area is full, the oldest backup is deleted. We’re going to lớn take a closer look now. Consider that you have sầu a data drive. Once Shadow Copies is enabled, it will allocate a storage area. The administrator can exercise control over how large the storage area for Shadow Copies really is; there is however, a minimum form size it must be and that is 300 megabytes. When a Shadow Copy runs, it will store recently changed files.

Looking at files on the drive sầu, let’s consider that some have had changes made lớn them. When the Shadow Copy service runs next, these files will be copied lớn the Shadow Copy data store. Now consider that another file has changed after the first Shadow Copy has run. Nothing will change in the Shadow Copy storage area until another Shadow Copy is run. The Shadow Copy service will then copy the changed file lớn the storage area. The process keeps repeating; each time files are changed và the next time the Shadow Copy service runs, the changed files are copied to the storage area. The storage area is quite efficient at storing changes made to lớn the files, rather than the whole complete tệp tin itself. So if you were to lớn keep changing the same files, all the time, the storage area will be able to lớn hold a lot of changes. At some point, the storage area will become full. When this occurs, the oldest Shadow Copy in the area is deleted when the next Shadow Copy service runs. Furthermore, Shadow Copies will only store up lớn 64 changes khổng lồ the file, after this limit has been reached, the oldest version will be deleted lớn make room for the new one.

Shadow Copies vs Backups2:43 – The next point we’ll discuss is that Shadow Copies are not replacements for regular backups. The administrator does not have control over which files are removed from the Shadow Copy storage. If the tệp tin you want is within the Shadow Copy storage area, that is excellent và you can restore the tệp tin, however if it has been removed, there is no way to restore it. If you want lớn make sure it is always available, you will need lớn store that tệp tin in some kind of backup solution. This concludes the đoạn Clip on Shadow Copies.
