The enhancement of litespeed SQL backup.
Dear all,
I have the following existing script using litespeed backup
Declare @filenumber int
exec master.dbo.xp_backup_datab
@GUID = N'7565C182-6AC1-4E5F-82B9-
@filename = N'\\REPO\Litespeed\Batch02
@backupname = N'Repository Daily iXCore_Port Full Backup',
@desc = N'Repository Daily iXCore_Port Full Backup',
@jobp = N'FlTb+IlqB9p9+MB4HPgZQg==
@compressionlevel = 11, @comment = '', @with = N'SKIP', @with = N'STATS = 10',
@filenumber = @filenumber output
exec master.dbo.xp_restore_veri
@filename = N'\\REPO\Litespeed\Batch02
@jobp = N'FlTb+IlqB9p9+MB4HPgZQg==
I have tried to add "@threads =16," and change compressionLevel to 11, but the total time doesn't change much.
Any suggestion on how to optimize that?
Also any link show me how to implemetn full backup + differential backup + retentation period using litespeed?
any way to improve the speed and size ,etc will be good !

You could try backing up to multiple files? I have seen large performance increases when doing this, especially when writing out to separate file systems too.

ashilo,
Compresslevel=6 is the best ?
"@threads =2*your cpu count"
I tried that before but I don't see much increase! probably the backup verification still spend a lot of time.
Any thing to improve the verification speed ?
EvilPostIt,
Yes, but the litespeed do not have this option for me, am I miss anything. Redgat toolbelt can do this ? how can I do this in litespeed and after that I can still easily restore the MULTI backup files?

EvilPostIt,
the version of Litespeed we are using are 4.8.3.00025. What is the highest version we can directly upgrade from ?
