Log Supplements 

Using the option -o dist|time[,time|dist] and/or the option -w|-verify causes the detail log to be supplemented (the effects are similar for all the SAP utilities). See -o|-output or -w|-verify (for BRBACKUP), -w|-verify (for BRARCHIVE).

• position Position of the file on the volume.
• size Size of the file (in bytes).
• rate Compression rate when hardware or software compression is used. The compression rate is specified as: <value>:1 , value=<size (file size before compression) >/<compressed (file size after compression)>.

• compressed Size of the file (in bytes) after their compression.
• duration Indicates how long the last backup of this file took ( <minutes>:<seconds> ). This enables you to approximately estimate the duration of the backup.
• speed Throughput of the backup (calculation: speed=<size>/<duration> in MB/h)
• name File name

This information is listed for each volume (tape or disk). The last line ( total ) shows the totals or averages of the individual columns. An asterisk ‘*’ in column duration indicates that the BRBACKUP optimized distribution of the files among the backup devices for time (only relevant for parallel backups). The goal of this is to balance the load of all the BRBACKUP backup devices. When optimization by time was not possible BRBACKUP attempts to equally distribute the data volume.

During the processing, SAP tools issue a timestamp ( BR284I Time stamp YYY-MM-DD hh.mm.ss, elapsed time: <minutes>:<seconds> ) after every important event, e.g. more often than normal. This information can be used, for example, to track how much time was actually required for a backup (<timestamp after operation complete> minus <timestamp at operation start>); in the case of a parallel backup, these two timestamps need not appear one after another.

After the log entries on the backup flow, a list appears with information about the saved files.

This information was described above with the use of option -o dist . Of course, the values in column duration have now been updated. If software compression is used, the current compression rate can also be determined.

• Indicates that verification is active and that twice the backup time is required as a result.
• Information about which volume was used for the verification run, which files will be restored where, and the result of the check (e.g. BR363I Verification of backup of <file name> successful ).
