Hello,<br />
<br />
My current environment : &nbsp;Windows 2008 R2 Backup<br />
Full Server Scheduled backup is done daily on a USB external drive<br />
<br />
Strange Behavior of the backup process:<br />
<br />
From time to time, without understanding the reason, all previous backup are erased and all backup process starts over (as if it was &quot;day 1&quot; of backup history)<br />
<br />
That means that I cannot restore from &quot;previous backup&quot; (backup of last week for example) since all backup history is erased <br />
<br />
Does any one knows why does this happens? <br />
<br />
If the USB drive if full, only &quot;old&quot; backups should be erased not &quot;all backup history&quot;, is it? <br />
<br />
Thank you for your help

Hello,

My current environment :  Windows 2008 R2 Backup
Full Server Scheduled backup is done daily on a USB external drive

Strange Behavior of the backup process:

From time to time, without understanding the reason, all previous backup are erased and all backup process starts over (as if it was "day 1" of backup history)

That means that I cannot restore from "previous backup" (backup of last week for example) since all backup history is erased 

Does any one knows why does this happens? 

If the USB drive if full, only "old" backups should be erased not "all backup history", is it? 

Thank you for your help

Windows 2008 Backup

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.
