Don’t misuse the word “Backup”
The process of backing up, refers to the copying and archiving of computer data so it may be used to restore the original after a
data loss event.
File Syncing
vs.
Full Backup
Syncing
Creating two identical copies
that is updated both ways
What Happens
If a file or change is detected on drive A, drive B is updated.
If a file or change is detected on drive B, drive A is updated.
If you delete a file, both are deleted.
Mirroring
Creating two identical copies
that is only updated one way.
What Happens
We want our second drive to be the same bit for bit.
If the main drive fails, we swap and use the mirrored drive until we rebuild a new one.
Copying
Selecting all files from one hard drive
and copying them to the other.
What Happens
There is no link. If you change something on drive A, drive B never sees it.
Use this when you are giving away copies.
Full Backup
Create a compressed copy of every file; deleted files, multiple changes to that file,
every file you ever created.
What Happens
This will require more storage than your original hard drive and it can only be read or
restored with software.
This is a perfect format for offsite backup.
Recap
MIRROR - two external hard drives that are updated automatically when a change is
made. There are plenty of free utilities that can do this.
Recap
FULL BACKUP - creates a compressed copy of every file and keeps multiple
versions of the file.
Normally, this is a paid option.
