Yeah, I was just going to ask you that. &nbsp;This could be the ONLY reason.<br />
<br />
good fix<br />

started a new job, and inherited a potential hornet's nest of a mess...<br />
<br />
i plan on upgrading the symantec backupexec 11d to 12.5 this coming weekend.<br />
<br />
So before the weekend i want to make sure the differential and full bakcups on friday complete. and not carry over any issues to the new version.<br />
<br />
lately some of the backups are imcomplete, as i switched off the brick level backup in favour of the IS agent.<br />
<br />
and only one tape had been put into the library for last nights backup, which of course 800gb compressed should be more than enough for cover 2 exchange IS servers.<br />
<br />
&nbsp;as the full backup last friday was only 498GB, yet it went over several tapes, 7 where in the library at the time.<br />
<br />
so today i found out that the backup exec 11d thinks that the tape caacity is only 196GB each... now that cannot be right .<br />
<br />
any ideas?<br />

started a new job, and inherited a potential hornet's nest of a mess...

i plan on upgrading the symantec backupexec 11d to 12.5 this coming weekend.

So before the weekend i want to make sure the differential and full bakcups on friday complete. and not carry over any issues to the new version.

lately some of the backups are imcomplete, as i switched off the brick level backup in favour of the IS agent.

and only one tape had been put into the library for last nights backup, which of course 800gb compressed should be more than enough for cover 2 exchange IS servers.

 as the full backup last friday was only 498GB, yet it went over several tapes, 7 where in the library at the time.

so today i found out that the backup exec 11d thinks that the tape caacity is only 196GB each... now that cannot be right .

any ideas?



why are my LTO3 tapes showing a capacity of 196GB when they are meant to be 400GB/800GB

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.
