Hi there,

I was trying to restore a huge data to local harddisk from an offline backup harddisk. There are 36,225,746 files and the data size is 1.7TB.

Steps to restore data:
1. Rebuild catalog using bscan
2. bconsole > restore > option 3 "Enter list of comma separated JobIds to select" > enter {jobid} > mark folder_to_be_restored

After entered "mark folder_to_be_restored", it took about 28 hours to show $ prompt and let me proceed to enter "done". Not sure why took so long. Is it possible to do some tuning? I could see there is a process "bacula-dir" which occupied 4GB memory only. While postgres processes are below 2GB memory. There are 7.7GB is free and 3.5GB for cache.

System configuration:
OS: 2.6.35.14-106.fc14.x86_64
Mem: 16G
Partition1(for OS): RAID1

#postgresql.conf
shared:2GB
effective_cache_size = 8GB
maintenance_work_mem=512MB
work_mem:128MB
wal_buffers = 8MB
checkpoint_segments = 64
checkpoint_timeout = 20min
checkpoint_completion_target = 0.9
synchronous_commit = off

#sysctl.conf
kernel.shmmax = 6442450944
kernel.shmall = 4194304
