OK. If I understand correctly, rsync compares against the last full backup and since there is only one backup, you're saying that the incrementals will get larger and larger? However, the machine I am backing up is different. Basically the full backup I have done wil NEVER change. The user only makes ADDITIONS to the full backup and does not edit old files or anything; in fact, the data on his machine is essentially static data. It is itself a kind of mini-storage server. What you have highlighted would be relevant if I was to back up his volatile laptop, which is like any other client. So my reasons for doing incrementals forever are correct, the question is HOW can I setup such a routine?

Be sure you understand how rsync incrementals actually work before you do that. The comparison is always done against the most recent full backup, so as that copy ages you will repeated pull a growing set of all files that have changed since then for every incremental run. An rsync full backup, on the other hand, takes more real and CPU time at each end because it compares all files regardless of the timestamps, but it takes very little more bandwidth - and will likely result in less bandwidth being used for the next run. -- Les Mikesell [EMAIL PROTECTED] ------------------------------------------------------- This SF.Net email is sponsored by: Power Architecture Resource Center: Free content, downloads, discussions, and more. http://solutions.newsforge.com/ibmarch.tmpl _______________________________________________ BackupPC-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/backuppc-users http://backuppc.sourceforge.net/ ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
