RE: SAS/Fibre Channel interface for LTO4

2007-12-11 Thread donald.ritchey
Our fibre channel devices show up as scsi devices on both Tru64 UNIX and HP-UX. I would expect most UNIX systems to behave the same. The underlying drivers are the same, as I understand it (FC being a serialized version of SCSI). Best wishes with the implementation. Don Ritchey IT ED RTS Tech S

RE: Encryption, compression

2007-10-30 Thread donald.ritchey
In my (admittedly limited) experience with encryption and compression, the rule of thumb has always been to compress first (removing exploitable redundancy and pattern repetitions) and then encrypt. It also has the advantage that you are encrypting less volume and reducing the exploitable "surfa

Actually, the time period to avoid is Sunday morning from 0100 to 0300, since you will get hit as described below, except that the period of Fall danger is from 0100 to 0200 (all of these entries will get run twice). Fall DST causes the clocks to reset at 0200 back to 0100, so that period gets

The various dump programs on Solaris need access to the raw device for the file system. The rundump command is set-uid root so it can make the backups, but the amcheck portion is not. The solution I found for my Solaris systems was to change the group membership to the 'amanda' account to the gro

The command you should run is: lsof -I :amanda Which should show the inetd/xinetd process listening on the amanda port (UDP port 10080). The output should look something like this: ritcdx> lsof -i :amanda COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME inetd 1285913 root

Problems with new Amanda release (2.5.0p2): amcheck not reporting tape errors via e-mail

2006-07-11 Thread donald.ritchey
I recently upgraded the first of our Amanda installations to 2.5.0p2 ] and found an unwelcome surprise: amcheck no longer reports tape problems via e-mail from an amcheck run out of the Amanda user's crontab file. We have amcheck set to run every day at 1500 to warn us if we have forgotten to ch

RE: Backing up subversion repositories (From a windows subversion server)

Obvious choice (probably not suitable, but no harm in suggesting it): Is there space available (or can be made available) on the tape server? If so, the second backup is local to the Amanda tape server. Another possibility: Are there network connections available to put up a local, isolated conn

RE: tar returned 2 error???

2005-08-24 Thread donald.ritchey
For UNIX systems, return code 2 is "No such file or directory" or "File not found", depending on the OS. This information is found in the /usr/include/errno.h on most UNIX systems (or wherever your version of UNIX stores the programming include files). Most programs will exit with a failure
