Backup to file fails at 4GB (FAT32 limitation?)

Postby MaxG » Mon Feb 13, 2006 9:27 am

Hello Good People,

I have installed the 30 day trial on a XP Pro machine to test BAs functionality. I scheduled a default job to back-up local C: and save it to an iOmega 80GB USB HDD. The backup ran at the time scheduled but failed with the following error report:

Date performed: Monday, 13 February 2006 00:00:04
Label: Sunday
Job name: Default job
Backup Method: Full
Backup Mode: Overwrite
Destination: File - on H:\BUPs (Volume: IOMEGA_HDD)

Checking files and directories to backup
-- All selected files and directories are available for backup

Phase One backup operation - errors occurred.

Total bytes: 4,284,272,389
Total files: 11,831
Total directories: 1,789
============================================================
Phase One backup log

Backup Status
Operation: Backup
Active backup destination: File
Media name: "2006-02-13.bkf created 13/02/2006 at 00:00"

Backup (via shadow copy) of "C: System"
Backup set #1 on media #1
Backup description: "Set created 13/02/2006 at 00:00"
Media name: "2006-02-13.bkf created 13/02/2006 at 00:00"

Backup Type: Normal

Backup started on 13/02/2006 at 00:01.
End of Media encountered while backing up to non-removable media.
The operation was ended.
Backup completed on 13/02/2006 at 00:11.
Directories: 1789
Files: 11831
Bytes: 4,284,272,389
Time: 9 minutes and 58 seconds

The HDD is formatted in FAT32... and I can't recall whether this is a FAT32 file size limit or not, or whether something else causes the problem. The HDD has 40GB available disk space and C: has 20GB to be backed up.

Any help or pointer in the right direction would be appreciated. BA is eventually going onto a SBS2k3 server with the intent to use large HDDs connected in the network as backup media.

Thanks and regards,
Max

Backup to file fails at 4GB (FAT32 limitation?)

Well, well... looks like silly me :oops:
I changed the bkf destination to another HDD formatted in NTFS; the backup is still going and passed the 7GB mark; looks like it will finish.
Oh dear, and silly me again: FAT32 has a 4GB file limit. (just googled it).

Apologies for posting something that was easily answered with a little more effort of mine.

Thanks,
Max

"Convert" can change the drive format without eras

Postby MaxG » Tue Feb 14, 2006 11:26 am

Hi Justin,

Yes, in hidsight I should have known :D

There is another way to change the drive format without loosing the data; at least in XP: CONVERT driveletter: /FS:NTFS, converts FAT to NTFS... but in doing so one will loose the ability to utilise the drive under Mac OS and other OSes that do not support NTFS partitions.

And I can also confirm BA works, and completed the backups I intented.

Thanks and regards,
Max

Hi All,

I was pretty excited when I found this thread as I have the exact same problem, backup fails at 4gb.

I followed the instructions and I am already formatted as NTFS. Any other ideas what I can do?

thanks

Hi Pam,

It's Stuart here from the BackupAssist team, thanks for your post.

Did you re-format the drive at all just to refresh the drive (I have seen this happen previously).

If you have done this and it's still failing at 4Gb, would you be able to provide some diagnostic information as
this gives us a lot of information which we can use to help resolve your issue.

To send us diagnostic information please follow these steps:

1) Go to Contact Support (from the bottom-left corner of the console) -> Contact Support
2) Fill out the form and ensure that the Submit system diagnostics checkbox at the bottom is checked.

If you have anything to add Pam, please either reply to this post or send us an e-mail directly at support@backupassist.com.
