File System Backup....
A user on Red Hat Linux AS3 reported that overall system performance degrades badly while running a daily OS-level filesystem backup (using cpio) of machines hosting Informix servers, and asked whether a better third-party backup tool would help. Responders questioned whether the problem was really the tool, suggesting checks of tape drive configuration, whether the backed-up filesystem shares devices with the Informix dbspaces, sar I/O activity, whether dbspaces are raw or cooked (and which filesystem type), and what block size/parameters the backup uses. The poster did not reply further, so no resolution is recorded.

Hi, Looking for advice on a file system backup of our IFX servers. We have noticed that system performance goes in the dumper when we are performing a daily file system backup. We are currently using cipo for this task. Is there a better 3rd party tool that you folks have experience with, and, that seems to mitigate this problem? Any other suggestions or advice? Thanks in advance for your help. Tam.

I'm a bit curious why performance should suck when running an OS backup ... possibly your tape drive isn't setup correctly? -- Bye now, Obnoxio "... no bill is required as no value was provided." -- Christine Normile -- This message has been scanned for viruses and dangerous content by OpenProtect(http://www.openprotect.com), and is believed to be clean.
is your filesystem on the same devices as your informix dbspaces? what does the sar i/o activity report?

Additional questions: - Are your Informix dbspaces in raw devices or cooked files? If cooked files, in which type of filesystem are they places (ext2, ext3,Reiser,...)? - What are your parameters used for backup operations (block size,...). I assume that you use cpio (you said cipo)?! Darko Krstic
