Hello,
Please review storage node or snapimage ( if still available) option for
this client.
How I can enable local logging on the EMC networker client.
If you run the client by script, then -v ( each extra v will
increase the logging level) with the save cmd will do it ( logs will
go to savegrp log)or you can do verbose logging for the group. ( I would
be very careful with either option, as the log file fills up, it
could adversely impact your backup & server performance, you
will get failure messages without extra logging ( i.e open files etc)
- Is it possible not to dump the full filesystem for each drive prior to
backing up data?
You will need to look into Native OS capabilities, i.e VSS, also
look into change journal to make use of it's capabilities
- Is it necessary to put a hughe amount of physical memory in the server
for backup purposes only?
I don't think so, however, expect backups to run very long time,
unless you breakup the data in various saveset and configure Legato
backups to be spread out. ( How much data and files are you referring too
?)
If you cannot get SN capabilities , try and serrate file system if
possible to different logical disk & spread out your backups, this way you
may gain slight advantage on read access & add a robust raid controller ,
optimized for read. ( This are optional steps and will only go so far)
Does your backup go to tape or VTL ? You may gain slightly better
performance if you use disk or VTL backups vs Tape ( again few other may
disagree)

Window 2008 memory and logs
Dear All,
I'm working on getting a Windows 2008 x64 server with a very large file
system to backup with EMC networker. My conclusions so far watching the
performance counters and tools on the server:
- For each saveset a save.exe process starts
- Each save.exe process creates a complete directory listing in memory
regardless of the path to be backed up
- There is default no log locally on the Windows 2008 server.
As this is a server with a very large filesystem, the complete directory
listing for each save.exe process will put several GBs of data into
memory, causing memory paging and performance issues. In the end the
backup completely fails for all savesets other than some system VSS save
sets.
I'd like to know:
- How I can enable local logging on the EMC networker client.
- Is it possible not to dump the full filesystem for each drive prior to
backing up data?
- Is it neccesary to put a hughe amount of physical memory in the server
for backup purposes only?
Cheers
