B.2 SLS/MDMS V2.x to ABS/MDMS V4.x Migration
The name of the Save request(s) created will be same as the SBK file, appended by the
“_FULL”, “_INC” or “_SEL” suffix. The appended suffix indicates the type of backup that was
performed in SLS.
Each SBK file when converted can produce a single or multiple Save requests. This discretion of
generating a single or multiple Save requests depends on the following conditions:
• QUALIFIERS_n differ in the type of operation (see Example 12–1, “Qualifiers_n differing
in the type of operation”)
• More than 24 include specifications are found in a single SBK file (see Example 12–2,
“More than 24 Include Specifications”)
Example 12–1 Qualifiers_n differing in the type of operation
• SBK file name: Example1_SBK.COM
• Include Specifications:
– Files_1:== Disk$User1:[Example]*.*
– Files_2:== Disk$User1:[Example]*.txt
• Qualifiers_n:
– Qualifiers_1:== /Image ! Full backup
– Qualifiers_2:== /Since=Backup ! Incremental backup
In the preceding example, the nature of backup operations performed are different. One type of
Save request when executed takes the entire disk backup whereas the other type of Save request
when executed takes only differential/incremental backup.
After the DCL command procedure “Example1_ABS.COM” is executed, the following ABS
Policy objects are created:
• Archive class: Example_ABS_SC
• Environment: Example_ABS_ENV
• Save:
– Example_ABS_FULL_1
– Example_ABS_INCR_1
Two Save requests are created from a single DCL command procedure to implement the Save
Policy object. This is because in ABS, a Save request can either perform a Full backup, Incremental
backup or a Selective backup and not a combination involving any of them.
If all the QUALIFIERS_n specify the same type of operation and there are fewer than 24
FILES_n specified, then the conversion utility produces a DCL command procedure, which
when executed provides a single Save request.
Example 12–2 More than 24 Include Specifications
• SBK file name: Example2_SBK.COM
• Include Specifications:
– Files_1:== Disk$User1:[Example]*.*
– Files_2:== Disk$User1:[Example]*.Txt
