Title: FILE System Post by: [[EUR]] HoloGram on February 19, 2004, 07:54:27 pm What is the better OSX Filesystem UNIX USF or the MAC OS Extended ( Journaled ) ???
Whichone do you use? Title: Re:FILE System Post by: c| Splinter on February 19, 2004, 08:05:11 pm Mac OS Extended Journaled. The journaling feature means that if your system gets screwed you can revert to a previous state of when things were working well. It's basically like saying, on Feb. 12th, things where looking good, so set everything back to how it was that day. Once you do that, anything that you did since that date (i.e. installed new programs, changed settings in the system prefs) will be gone. But it is a handy recovery tool.

First, UFS is incompatible with a good number of programs. This has to do with a myriad of reasons, one being case-sensitivity. However, it also lacks journaling, one of the big pluses of the newest version of HFS+. Splinter, you are a little off in what a journaled file system is. A journaled file system is useful in data recovery in case of a system crash. All file transactions are written to the journal. If a crash occurs, upon reboot the journal is replayed and the integrity of the data is confirmed. Any blocks found to be corrupted on the crash are repaired.

Only reason not to journal is if you transfer huge amounts of data ... ie if its drives being used in a file server or somthing...

No, that's exactly where you want to be using a journaled file system. If your file server goes down, you don't want to lose any recently transferred data. Yes, you do take ~10% hit on write performance (read is unaffected), but this is well worth it if you care about the integrity of your data. Title: Re:FILE System Post by: BFG on February 21, 2004, 02:46:02 am Well ace in this situation i was assuming you would have a backup system which is seperate. The performance hit can be pretty extream on large file servers and where speed is vital journalling dosn't help.
All depends on your individual set up i suppose. |
