DB2 backup question

Dear all,

Currently, I am using offline full backup for my working DB2 v8.1 for data
protection. The backup image will be dump to disk and then compressed by
bzip2.

However, the current DB size was over 3G and this exceeded the bzip2 limit
for compression. I have try the compress option in db2 backup command,
however the compression ration seem not as good as bzip2.

Could anyone suggestion that is it possible to break down the backup image
into parts with DB2 backup command option? Or could db2 backup command using
the bzip2 library for compression (I have tried the comprlib option, but it
isn't work and doc support is not much ..)?

Thanks in advance!

Henry

I assume you have FP4 or higher? That was the first version that supported
compression.

If you specify multiple paths on the "TO" command in the backup, DB2 will
split the file among the paths.

This is maybe a dumb question but I couldn't find a definitive answer on BOL. Looking at my backup script. If I issue a CHECKPOINT, does this truly force all transaction log entries to the data file? Therefore, making it unnecessary to BACKUP log (just BACKUP database is needed). Louis

I've a question regarding db2 (V8.1) and database backups going to a storage manager like TSM for example. As I can see in the storage manager if I backup the complete database over the TSM API (no tablespace backups) the backup images is stored as a single backup object. Later I will be able to restore the complete database from this...
