[BackupPC-users] backuppc 3.2.1 incremental SMB backup question

2012-11-02 Thread Jim Stark
I'm running backuppc 3.2.1 on Linux Mint 11, backing up a machine (A) which has SMB (as opposed to rsync/tar/...) as the only available backup mechanism. An initial full backup of A is fine, but a subsequent incremental backup does not backup files which were added to A since the full backup. It

Thanks for the prompt reply. Machine A is an old Buffalo TeraStation. Ironically, it is running Linux likely even has rsync, but as a practical matter, SMB is the only available access mechanism. 1) You can touch the files, or copy them in such a way that their times change No shell access to

Mount the buffalo with smbfs or similar into a unix/linux machine and let touch run. Yes, thanks. I could do that. On Fri, Nov 2, 2012 at 11:11 AM, Arnold Krille arn...@arnoldarts.de wrote: Jim Stark jstarkjhea...@gmail.com schrieb: Thanks for the prompt reply. Machine A is an old

My concern is that to verify that a file can be pooled, it first has to be brought over from machine A (true?). Thus, even if it is ultimately pooled only costs 1 hard link in the backup for the host, there is all of the full backup overhead on machine A and all of the network traffic to get it
