Backup Data Set Record Field

This is the section for backup data set information. If backup information records are requested, one record is created for each backup version represented in the BCDS. The record type for this record is B.

Name: Description
UBDSNAM: Identifies the name of the data set to which this backup version applies.
UBINCAT: Indicates the cataloged version of a data set name that is used by multiple data sets. For example, two different data sets (one cataloged and the other not in the catalog) can have the same name. This bit indicates which data set is being referred to with the data set name. When this bit is set to a 1, this backup refers to the cataloged data set.
UBNOENQ: Because DFSMShsm was directed not to serialize, the data set was unserialized while it was backed up.
UBBWO: Indicates that this data set was backed up while the data set was a backup-while-open candidate.
UBNQN1: The data set was unserialized while it was backed up. Even though the serialization failed on the first attempt, DFSMShsm was directed to accept the backup result without a retry.
UBNQN2: The data set was unserialized while it was backed up. The first backup attempt failed because the data set was in use and DFSMShsm was directed to retry. DFSMShsm accepted the result of the retry, even though serialization failed again.
UBDEVCL: Identifies the device on which the backup version is currently residing (DASD or tape).
UBDSORG: Indicates the data set organization.
UBDSIZE: Indicates the size (in kilobytes) of the backup version. If compaction is used, this value represents the compacted size.
UBBDATE: Contains the time and date that the backup version was made for the data set. The format is packed decimal. The date (yyyydddF) indicates the year(yyyy) and day(ddd). The time (hhmmssth) indicates the hours(hh), minutes(mm), and seconds(ss), including tenths(t) and hundredths(h) of a second.
UBCLASS: Contains the SMS data class, storage class, and management class of the data set at the time the backup version was made for the data set.
Note: If UBSCLNG, which contains the length of the storage class name, is zero, the data set was not SMS-managed at the time that this backup copy was made. If UBSCLNG is non-zero, the data set was SMS-managed when this backup copy was made.
UBRECRD: Indicates the data set record format.
UBRECOR: Indicates the VSAM data set organization.
UBBKLNG: Indicates the block length of this data set.
UBRACFD: Indicates, when this flag bit is set to a 1, that this data set was RACF-indicated at the time that it was backed up.
UBGDS: Indicates, when this flag bit is set to a 1, that this is a backup copy of an SMS-managed generation data set (GDS).
UBREBLK: Indicates, when this flag bit is set to a 1, that this is a copy of an SMS-managed system-reblockable data set.
UBPDSE: Indicates, when this flag bit is set to a 1, that this is a backup copy of a partitioned data set extended (PDSE) data set (DSNTYPE=LIBRARY).
UBCOMPR: Indicates, when the flag is set to 1, that the data set is in compressed format.
UBALLSP: Indicates the space (in kilobytes) that was originally allocated on a level 0 volume when this data set was backed up from that volume. If backup is done while the data set is migrated, this value represents the size of the migrated copy of the data set. If the data set is compacted during migration, the size might be smaller than the original level 0 data set.
UBUSESP: Indicates the space (in kilobytes) of actual data in the data set at the time that the data set was backed up.
UBRECSP: Indicates the estimated space (in kilobytes) required if this data set is recovered to a level 0 volume of similar geometry, using a similar blocking factor. Actual space used will depend on blocking factor and device geometry.
UB_USER_DATASIZE: Contains, when UBCOMPR is set to 1, the size (in kilobytes) this data set would be if not compressed.
UB_COMP_DATASIZE: Contains, when UBCOMPR is set to 1, the actual compressed size (in kilobytes) of the data set.
