Home -> Community -> Mailing Lists -> Oracle-L -> RE: Logical Backup for a large database
I would suggest to export schema by schema and schedule the jobs to run different time. In the export job, use pipe file at the unix level to compress the export file. The command is as follows:
To export and compress at the unix level...
mknod export_pipe p
compress < export_pipe > export.dmp.Z
exp ....... file=export_pipe
To import and uncompress...
uncompress < export.dmp.Z > export_pipe
imp ....... file=export_pipe

Last week one of my user dropped a table since we don't have any backup except for rman backup. It is not allowe me to do any recovery on 7/24 database. Anyway we recreate the table(we are lucky, this table hold parameters)
This make me think of situation of lossing very important big table. We have about 1000 tables with bigget one of 8GB .
Is there any idea how to perform a logical backup on a database with 150GBs. Or take a TSPITR in case of those kind of thing happen again. From my case, imp/exp looks impossibe from point of view of timing and spacing. The question will be the same for TSOITR on large database. Is there any other way to prepre those kind of situation.
