If we had the hash values saved when BackupPC_link runs, we could reconnect the links much faster.
In the case of an off-site backup, I wonder if the cpool could get copied directly and the per-pc files are changed such that they are no longer hardlinks but simply contain the hash. The idea here is to reduce the time it takes to make the offsite copy. Obviously, to pull it back, some reconstruction needs to take place. But that's only in the event of disaster, right? - Wade -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Les Mikesell Sent: Wednesday, December 21, 2005 12:49 PM To: Marty Cc: [email protected] Subject: Re: [BackupPC-users] Cpool question On Wed, 2005-12-21 at 12:30, Marty wrote: > That brings up another question for anyone here -- does cp -al work > (within the filesystem) on the pool, or on the cpool, or is it also > prohibitively time-consuming?

You'd need -aH to do hardlinks, but it doesn't really help you to have copied the data under the pooled names anyway. When you rsync the pc directories it will copy all the data under the new name since it has no way to connect that to the pooled name without the time/memory-intensive step of including the pool in the rsync run. There is a linux program called 'hardlink' that will do a brute-force matchup of indentical files under the specified directories and convert to hardlinks. I'm not sure how fast it is but I'd expect it to be slower than something that knows the backuppc name conventions. -- Les Mikesell [EMAIL PROTECTED] ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
