> +skip: . Note: the plus (+) sign means that it applies to the named directory and all of its subdirectories (i.e. recursive). How to configure ports for Legato? (ports configuration in firewall) In client side: nsrports, show ports used by NSR client; rpcinfo -s uslgto2.melonm.com, show ports used for connection (optional) # nsrports -S 7937-7940 --> restirct ports used in the client side (these 4 ports are sufficient). Open the inbound ports in the firewall for the following 4 ports, so both clients can talk to Legato server/Storage node inside the firewall. Usws1 --> ports (7937-7940) --> uslgto2/uslgto3.melonm.com In the server side, restrict the ports based on the following fomula: 12(default)+number ofJukeBox+ 2*number of devices (tape+aftd) + 5 eg, 12+3 (Jukeboxes)+ 2*12 (number of tape/disk devices) +5=72 So the total port will be: 7937-8080 (adding 71 more ports to be on the safe side on top of 72 ports, 7937+72+71) How does multiplexing work in NW??(would like to increase the amount of drives used on one save group) The number of drives used for backup is dependent on different parameters, mainly on drive sessions. In the properties of the drive check the number of target sessions. By default it is 4 so you can increase it to 8. Also verify that the client,storage node and networker server parallelism is more than 8. In addition to the above settings check the number of clients in the group. If the backup is targetted to drive with 8 target sessions first it will start backup of 8 savesets to single drive, if the number of savesets is more than 8 it will then start the backup to next drive.

If there are storage node needs to be configured (2 nodes to see same drives), follow this instruction for configuration. The key to all same drive has 2 paths (one to Networker server and another to Storage node). Each time hardware changed (eg, replace a drive), the library needs to be reconfigured in Legato using jbconfig. NDMP Backup Regarding to incremental backup using NDMP The NetWorker software does not support incremental backup settings for NDMP backups. If you select the incremental setting, the NetWorker server performs a full backup. However, you can schedule level backups to function like incremental backups. For example, complete a full backup on day 1 and level 1 backups on days 2 through 7. Incremental will not work with NetApp if you forget to specify

"UPDATE=Y". This parameter actually instructs Ontap NDMP to update the dumpdates file which is used to determine what should be backed up. To view all NDMP dump history & levels on NetApps, see file: /vol/vol0/etc/dumpdates Backup Command: nsrndmp_save -c hostname_of_nas_interface/client_name -s backupserver -I indexserver -M -T dump; NDMP Restore through Legato nsrndmp_recover -c usnas2 -s uslgto2 -m usorarestore:/u6 -S 3439474549 "/vol/vol2_nas2/WPSysMan/file.pdf" NDMP Save through storage node public nic nsrndmp_save -c usnas2 -M -T dump -b "XING NDMP" -P uslgto3v -y "11/07/08" /vol/vol0/home # uslgto3v is pub nic of storage node. Command is run in storage node. How to exclude files/dirs from NDMP backup of NetApps filer? To exclude files or directories from an NDMP backup of a NetApp filer, use the EXCLUDE= option in the NDMP Client resource's Application information field. EXCLUDE= takes a comma separated list of file and/or directory names to exclude from the backup. This is equivalent to the X option of the dump command. The following are rules for specifying names in the EXCLUDE= list: If a specific file or directory is to be excluded from the backup, the exact name of the file or directory must be used. An asterisk (*) can be used as the wildcard character. The asterisk must be either the first or the last character of the string. Each string can have up to two asterisks (one in the front and one at the end). If a file or directory name contains a comma, the comma must be preceded by a backslash to denote special character. This is because comma is used in the EXCLUDE= string to separate values. The EXCLUDE= list can contain up to 32 names.

Here are some examples: To exclude the 'tmp' directory from a save set, use EXCLUDE=tmp To exclude all .PST files from the save set, use EXCLUDE=*.PST To exclude all files or directories that contain the characters 'old' in their names, use: EXCLUDE=*old* To exclude all of the above at the same time, use: EXCLUDE=tmp,*.PST,*old* Recover Netapp filer's NDMP data nwrecover: Before starting nwrecover GUI, please change the directory to  /filermountpoint, then start nwrecover with command "nwrecover -s (nwserver) -c (filername)" or after starting nwrecover gui with command "nwrecover -s (nwserver) -c (filername)" , you need to expand the filer's file in the Select:. For example, /vol/vol*. Using command line: recover saveset nsrndmp_recover -c filer_name -s (NWserver) -S ssid -m (filername)::target_dir Recover single file: Recover To recover NDMP savesession in FP, using uslgto3 as recover server due to NIC (pub&priv) issues. Redirect "Bootstrap Completion" printout In Configuration--> Notification, specify "cat >  /nsr/bootstrap/nsr_bootstrap_`/usr/bin/date '+20%y%m%d'`" as action of "Bootstrap Completion" Create directory /nsr/bootstrap and we will get updated bootstrap information each day. If possible, setup rdist so whole /nsr directory will be duplicated to remote server as backup. Each day, the bootstrap information after each executed job will be saved into above directory instead of printing to physical printer by default.

Workaround: Clean up old decommissioned hosts index; Move the index to other location How to completely remove client from Legato (eg, for reclaiming licenses)? Perform a full bootstrap backup for group which has clients to be removed (eg, savegrp -l full -O -G Unix_Prd). Record ssid in case media index needs to be restored. Delete the client in NMC Stop nsr services Backup the client's index folder (/nsr/index/) Clear the cache by renaming \nsr\tmp\ folder to  \nsr\tmp_old_todaysdate Start nsr services Temporarily set the Autostart function on all Groups to 'Disabled' (it is best to perform the following when NW is idle) Run the following commands to verify, fix and purge the index and mdb records: nsrck -L6 --> this will take a very LONG time. Please make sure enough time is scheduled between backups. nsrim -X Set the Autostart function on groups that was changed in step 8 back to "Enabled". How to remove old hostnames from registering in NSR server? Search old hostname in nsr indexes: /nsr/res/nsrdb &  /nsr/res/nsrladb eg, grep */* /nsr/res/nsrdb & grep */* /nsr/res/nsrladb Edit the index file and remove the old hostname Retry the backup How to relocate client index to different location in Unix?

When done, removed hardcoded IP address and reboot the server. The server should be back with domain enabled. Legato Windows Agent Issues Not locate NSR server: First time when Legato Windows Agent starts, it will search for Networker server through broadcast. If Legato server is in a different network than agent, the search will fail and the agent gui will close. To fix this problem, append the server string after the executable, eg: "C:\...winworkr.exe" -s DMZ servers Name Resolution: Legato agent requires reverselookup working for both Networker server & storage node. For DMZ servers which have different DNS server, add IP/Hostname of Legato servers into C:\Windows\System32\drivers\etc\hosts If hosts file doesn't work, CREATE A NEW ONE. It is possibly corrupted but not evident to you. Holy smokes, it works for me. Turning off vss for specific drive VSS:h:\=off   How to backup Exchange server?

Tape Daily Recording & Archive Made one process in place to archive daily tape list offsite and upload to Windows shared drive. 2 Points about this process: We have daily clone in place at daytime, so any tapes within past 24 hours will stay in libraries until clones complete. Legato server is in Unix and shared drive/storage for archive is in Windows, so we have to resorted to Samba/Expect script in another middleware system for uploading. Here is the actual process flow: Schedule this job (dailyTapes.sh) to generate 2 reporting files (tapeReport.txt & tapeOffsite.txt). tapeReport.txt will be sending to various recipents by email while tapeOffsite.txt will be

uploaded to share drive to be (eventually) imported into SQL server media database. Above script will also copy 2 list files to Samba middleware server. Using this job (nsrOfftapes.sh) at later time to upload both lists into share drive. The upload script will use Expect script (nsrOfftapes.exp) with Samba client to upload. Once above process is in place, we have an automated process to generate offsite tapes and the list will be archived in central server for future reference. Daily Legato Routines (chkNSR.sh) checking interrupted overnight backup jobs Backup daily saveset Index (samething sending through email) to a local directory Replicate Index directory to a mirror site Regular schedule change on jobs Clone some archive logs of Oracle databases Daily Legato Media Database HealthCheck (nsrDBchk.sh) Check media database status and archive result. "-d" option for debugging This script will need to run when NW server is idle (eg, no device mount/unmount). Otherwise, all device mount/unmount will be automatically cancelled and on pending. How to calculate Data Domain usage per host through Networker (sizeCal.sh) Using "mminfo -avot" to get all savesets in DataDomain. Then produce a list of clients. Above script will calculate each host's space in DataDomain. Note: Since size produced from mminfo didn't have floating point, above arithmetic using BASH is OK. For adding arithmetic numbers, you must use programming tool such as "bc". Here is a script using "bc" for arithmetic operations with floating points (sizeFal.sh). How to save daily bootstrap information? Bootstrap is critical when the time comes to recover SSID and

you need to know which tapes contain it. You may be able to get some information from mminfo, but what happens if that client has been removed from Index (for reclaiming license, for example). In Legato GUI-->Configuration-->Notification-->Bootstrap->Action " cat > /nsr/bootstrap/nsr_bootstrap_`/usr/bin/date '+20%y%m%d'`" Now you should have a bootstrap text file saved to Legato directory each day every day. How to customize Savegroup completion email? By default, each day you will receive emails when savegroup completes. If you want to customize it (eg, add Savegroup name on the email subject), in the Notification-->Savegroup completion, add name of script to Action field:  /nsr/scripts/ savegroupEmail.sh
