' Elevate this script for Admin privileges in Vista The result is an 'Incremental' clone applying only file system changes detected between the source and the target. All the NTFS file system structures are copied to the target disk and any that do not exist or have been modified on the target disk cause the data records for each NTFS file or object to be copied as well. The two file systems are first verified that they originated from the same format command and then the target NTFS file system structures are analyzed for differences. The NTFS file system resident on the clone source is compared with file system on the target disk. The advantage of this is obvious, RDC offers similar a performance increase as an Incremental disk image offers over a Full image and enables regular clones to be a viable and fast DR solution. We wanted to build a clone solution that would effectively and rapidly copy only the differences between the source and target file systems. Reflect will verify the integrity of your file system Verification check that all files and folders data entries are correctly mapped to the file allocation table (FAT) or MFT Bitmap (NTFS)Īs with Rapid Delta Restore (RDR) the concept of RDR has been something that has been thought about for quite some time here at Macrium Software. To ensure backup integrity the 2 older incremental backups are consolidated with it to create a new incremental backup. Deleting the oldest 2 incrementals would cause the backup chain to be invalid as the oldest retained incremental requires the previous 2 incremental backups to complete the chain. After retention, the most recent 4 incremental backups are retained. The retention rules are set to retain 4 incremental backups. In the example below, before retention, there is 1 Full backup, 1 Differential backup and 6 Incremental backups. This is achieved by merging older Incremental backups when required. When deleting Incremental backups the integrity of the backup set is maintained by ensuring that the chain is never broken. When deleting Differential backups all linked incremental backups in the same backup chain (set) are also deleted. When deleting Full backups all linked incremental and Differential backups in the same backup chain (set) are also deleted This operation will delete the entire backup set.
