Difference between RAID/ WINDOW BACKUP tutorials

RAID is considered as LIVE BACKUP. Any mistake or change, good or bad will be backed up immediately. Biggest advantage of RAID is it is IMMEDIATE, ACCURATE and UP-TO-DATE. But same way any Accidental change, Deletion or Virus can make it blank.

Windows Backup will only happen when you schedule it to happen. You can backup your data on Tape Backup, Local HDD or Network Shared Resource.

  • You have to make organization strategy to backup up

  • Organization DATA (Most Imp)

  • Registry Files

  • Boot Files,

  • Active Directory and DNS Database

Using NTBACKUP Utility

  • The BACKUP utility allows you to take Backup and Restore earlier taken Backups. If the earlier data is lost, deleted, corrupted or even HDD fails then you can recover data by RESTORING earlier taken backups.

Backup type Options

  • NORMAL:- Backup all the files and set the Archive bit as marked for each file that are backup. To Restore we need only latest one set.

  • COPY:- Backup all the files and does not set the Archive as marked attribute for each file that are backup. To Restore we need only latest one set.

  • DIFFERENTIAL:- Backup only those files and that have not been marked as Archive, and does not set Archive Bit attribute for each file that are backup. To Restore we need LAST NORMAL BACKUP and LAST DIFFERENTIAL BACKUP set.

  • INCREMENTAL:- Backup only those files that are marked for Archive attribute and after backup mark each file that are backup. To Restore we need LAST NORMAL Backup and ALL INCREMENTAL BACKUP SETS in SEQUENCE.

  • DAILY:- Backup only those files that have been changed today and does not set the Archive attribute for each file that are backup. To Restore we need daily backup and last normal backup set for the restore process.
