psync makes no backups, it synchronizes!
Authored by: loekjehe on Jul 13, '02 08:47:06AM

I have problems with the use of the term "incremental backup" for psync. An incremental backup is a file containing a copy of all the files that have changed since your last incremental backup. Psync doesn't make an incremental backup. It doesn't do anything else than synchronising the target folder with the original. This process is not even making a "differential backup", since with a differential backup you have a full backup and a set of differential backup files.

I mention this, because synchronising volumes can have disadvantages to creating backup files because you cannot go back to an earlier situation (e.g. with virus problems or corrupt files etc.): with psync you always have a "fresh" full backup.

When you want to make "real" incremental or differential backups using a free CLI utility, I recommend hfspax from Howard Oakley (see www.versiontracker.com).

hfspax - backing up on OS 10.2
Authored by: chanlotus on Oct 07, '02 07:06:42PM

I need a compressed backup. hfspax has been working great for OS 10.1x. However,
it breaks in OS 10.2 returning error as followed and the backup is not complete:

hfspax: Read fault on usr/bin/hfspax <Invalid argument>

Has any experienced the same and is there any solution for it? It'll be great help
if anyone gives me a hint on it. I need that bad!!! Thanks in advance...

hfspax - backing up on OS 10.2
Authored by: bluehz on Oct 08, '02 09:00:01AM

I tried for over a month to get usable backups with hfspax. I never seemed to have any trouble actually creating the archives - but accessing the archive to extract any backup file was like pulling teeth. I finally gave up. Am now trying hfstar.
