Tushar: Is it necessary to do the optimize on each iteration? When you run an optimize, the entire index is rewritten. Thus each index file can have at most one hard link and each snapshot will consume the full amount of space on your disk. Asir On Thu, Jul 9, 2009 at 3:26 AM, tushar kapoor <

What I gather from this discussion is - 1. Snapshots are always hard links and not actual files so they cannot possibly consume the same amountof space. 2. Snapshots contain hard links to existing docs + delta docs. We are facing a situation wherein the snapshot occupies the same space as th

Ok If these are hard links, then where does the index data get stored? Those must be getting stored somewhere in the file system. Regards, Koushik On 18/04/09 12:35 PM, "Noble Paul നോബിള്‍ नोब्ळ्" wrote: yeah ,that is right but those are hardlinks http://linux.about.com/cs/linux101/g/h

When we run the snapshooter script, it creates a snapshot folder e.g. snapshot.20090418064010 and this snapshot folder contains physical index files which take space on the file system (as shown below). Are we missing anything here? -rw-r- 46 test test 59 Apr 17 23:26 _i.tii -rw-r

the snapshooter does not really copy any files. They ar just hardlinks (does not consume disk space) so even a full copy is not very expensive On Sat, Apr 18, 2009 at 12:06 PM, Koushik Mitra wrote: > Hi, > > We want to create snapshot incrementally. > > What we want is every time the snap shooter
