ArcServe 2000 Windows Change block size 3

[sluice]

I want to increase the backup block size for our HP DLT VS80 drive. There doesn't seem to be a relevant .ini file entry that I can find. Can anyone help?

In the registry go to : HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\BrightStor ARCserve Backup\Base\TapeEngine\Device#

Device # corresponds to the tape drive that will require a change in block size.

Click EDIT, then ADD VALUE
ValueName=DefaultBlockFactor
Data type = Reg_Dword
Data: 5, Hexadecimal
In addition to 5, the following values can also be chosen:

0 = 512 (default)
1 = 1,024 (1K)
2 = 2,048 (2K)
3 = 4,096 (4K)
4 = 8,192 (8K)
5 = 16,384 (16K)
6 = 32,768 (32K)
7 = 65,536 (64K)


I think the setting for 5 (16K) or 6 (32K) works best for DLTVS80

You might be stuck with poor performance. Version 11 needed a fix for a poor performance problem with this drive so chances are that 2000 also had the problem. However there will be no more fixes or updates for ARCserve 2000.

Same problems here.. Are there any updates or solutions available? I can't tell my client that his backup solutions sucks with drive support

Is it really the same problem? same drive same, version of AS, if not then it is not the same problem, if it is then the answer is above.

Poor performance with a DLT drive? Yeah I think it's the same problem.

But never mind. I deinstalled Arcserve and installed the latest veritas Backup Exec software.. Problem solved.

YES Cyklops !


I had the same issue

Arcserve 2000 with a brand new HP DLT VS80

I changed the block size as you wrote
I put settings on 5, and it is really fast nearly 20 times faster

Thanks again
