backup tape ejects early

July 23, 2008

Hi, I am backing up to a 4mm Data Tape (72GB) using the SBS Backup program

(with the Windows Backup program). I am trying to backup C, D and System

State. I have noticed over the last couple of weeks that the System State

has not backed up at all and it doesn't look like the D drive is being

backed up correctly either. When I check the tape in the morning it has

already been ejected but before this problem started it stayed in the drive.

Below is a copy of the latest log. I notice that the media is not being

found on the second part of the backup but why is it being ejected early? I

have reset the backup schedule but this doesn't seem to make any difference.

Re: backup tape ejects early

When that happens to me (we use Backup Exec), it means the tape is full....

Re: backup tape ejects early

You are backing up to media which has 36GB capacity (DAT72).

DO NOT believe manufacturer claims of 2:1 compression. You will be lucky to

get 1.3:1 on any 'normal' system.

Backup is working perfectly, your tape is too small. :-)

Re: backup tape ejects early

wouldn't the log file tell me that the tape was full? Also wouldn't the

message about the tape being full, please insert new media appear on the

screen if that was the case? Neither of these instances occur.

Re: backup tape ejects early

nah, the backup task runs in a separate instance of the desktop (normally)

so any alert does not get reflected to 'console'. It also, on SBS, runs in

the security context of 'backupuser' which is normally disabled and only

enabled by the SBSBackup task. I haven't tried but it's _probably_ possible

to sign onto the server as 'backupuser' when the account is enabled, you may

then see the 'please insert another tape'.

'The requested media failed to mount.' _is_ telling you the tape is full.

It's not intuitive, granted, but if you know NTBackup you get used to such.

Your tape is full. Get a bigger tape or reduce your backup. (former being

preferable to latter)

Re: backup tape ejects early

Hi Lenny:

While agreeing with SG, it has happened to my customers that it was just not

a good time to purchase different media, either tape or external hard

drives. There is another possibility, which I don't recommend except in

very extreme circumstances.

You can use NTBackup, not SBS backup and create a multi tape base backup

when you have time, as you will need to be available to change the tape.

Maybe start Thursday night and finish Friday morning or late in the day on

Friday, then use NTBackup and Task Scheduler to do Differential backups the

rest of the week.

Differential backups use the full backup plus the last tape to complete the

restore. The danger is that the last full backup, or the current tape will

be defective. It is worse if it is the last full backup, since you could

use the 2 day old tape to complete the restore, but that is nowhere nearly

as safe as all files every day.

Be sure to run the verify on every backup and test restore files from the

full backup as well as an occasional daily backup.

http://technet2.microsoft.com/windowsserver/en/library/7b36aa80-e68a-4276-8d82-a637a2f7ed871033.mspx?mfr=true

In the long run, get bigger media. Either External Hard Drives or a new

Tape Drive.

Re: backup tape ejects early

Hi, The Tapes we are using are HP Data72 C8010A. The total backup is 53GB

but it has been around this for ages give or take a little bit. Why would it

suddenly become full?

How can I be sure that the tapes are being used to their full capacity? Is

it within the Backup program?

Re: backup tape ejects early

I also can't see anywhere that would allow me to wipe the tape clean and

have a fresh start? I realise now why most people tend to use another backup

program.

I have thought about backing up to a removable HD but at the moment we back

up on a daily basis in a 2 week cycle. This could work with removable HD's

but we would need 10 of them and they are not as convenient as the Tapes.

Any thoughts?

Without wanting to dilute the main thread, what does everybody recommend as

a backup software?

Cheers

Re: backup tape ejects early

In my experience you get around 1.3/1 compression on tape backups, so 36

GB x 1.3 = 48GB is the realistic capacity of the tape, not 72GB. Your

log shows that around 12GB + 36GB was backed up before the tape end was

reached, which tallies with my estimated true capacity of 48GB. Your

tapes are fine, but you are trying to backup too much data. Check your

previous successful backup logs to see how much data you were getting

onto tape then.

You can download Treesize to discover where you are using most disk

space, then exclude non-critical folders from the backup. Typically, you

can exclude the WSUS folder and System Volume Information to save

serveral gigabytes. Remember to count you MDBDATA folder twice when

estimating the size of the backup because exchange is backed up twice,

once as offline file backup, and again as an exchange aware online backup.

Re: backup tape ejects early

The cost of USB hard disc have dropped considerably, while the amount of

space on these disks have greatly increased. It might be time to investigate

moving from tape media to hard disk. The next version of Server (server

2008) no longer supports disc to tape backup - obviously 3rd party

application will continue to support whatever backup media the customer is

willing and able to support.

One other solution to look into; how often do you replace your tapes. See if

a new tape changes the outcome. Old tape will degrade over time and it is

reasonable to expect it needs to be replaced (proactively) on a regular

basis. How often is cleaning maintenance performed on the tape drive?

finally, have you actually calculated the amount of data that is being

stored. As another reply mentioned, depending on compression to occur at the

maximum rate is not a good strategy. Higher compression is usually based on

application data (text, word, etc). If your backup has a significant amount

of binary/streaming data - you will not begin to approach a 2:1 ratio.

Compression is based on the possibility of representing (algorithemetically)

substantial portions of the data. binary storage is pretty "dense" and does

not respond well to compression.

I'm not sure you are understanding this: everytime the SBS backup runs,

it erases the entire previous contents of the tape so it is a fresh

start every time. There is nothing wrong with the SBS backup program.

HD's become expensive for long rotation periods. LTO-2 tape is the

logical step up from DAT-72. WD Passport USB drives are reasonably

portable and cheap, but I'm not sure about durability. The Dell RD1000

looks like a nice solution but it would be expensive with 10 cartridges.

The built-in SBS backup software is more than sufficient IMO, but if I

was going to spend money, I'd go for something like ShadowProtect

imaging software to do continuous incrementals. I wouldn't waste my

money on BackupExec.

Re: backup tape ejects early

thanks for that info. Using the Exclude folders... button I am unable to

locate either the WSUS folder (Which I can't find anywhere on the computer -

Windows Server 2003) or the System Volume Information.
