How to do hot backup using postgres
I tried to do pitr backup using Postgres 8.3.9 on windows. So I issued
SELECT pg_start_backup('test');
After I put the db in backup mode I tried to zip the data directory files
with 7z. However I encountered the following errors:
The process cannot access the file because it is being used by another
process.
C:\...\8.3\data\global1214
The process cannot access the file because it is being used by another
process.
C:\...\8.3\pg_xlog\00000001000000070000001B
...
...
But zip file was created.
Is it error ? How can I zip the files and perform a hot backup on windows?
Can anyone answer me ?
Thanks you very much

Exclude pg_log from the backup or rm that file at the recovery:
"You can, however, omit from the backup dump the files within the pg_xlog/
subdirectory of the cluster directory. This slight complication is
worthwhile because it reduces the risk of mistakes when restoring."
