Copy the Database Filesystem
We have a SAN migration and need to copy a 300 GB Database file system that needs to be copied to a new filesystem on a different disk.
Fbackup would be more reliable i beleive. Please suggest.

Re: Copy the Database Filesystem
fbackup would definitely be reliable if the database was shut down.
Also scp -p
dd
cp (if its on the same system or the target is available via NFS)
If the file system is on SAN based storage SAN utilities might be the quickest way to get the job done.

DD will be fast.

Re: Copy the Database Filesystem
While 'fbackup' and 'frecover' are certainly one way, I like 'pax'. See my responses in this thead (both the first and second ones):

Re: Copy the Database Filesystem
pax does look like a useful tool but saw some warnings as well.
WARNINGS
Because of industry standards and interoperability goals, pax does not
support the archival of files larger than 2GB or files that have
user/group IDs greater than 60K. Files with user/group IDs greater
than 60K are archived and restored under the user/group ID of the
current process.

Re: Copy the Database Filesystem
If you are on 11.23 or 11.31 the old limitations of 'pax' have been lifted:
