Backup policy recovering speed slowly (disk)
Dear NetBackupers, We have a NetBackup version 8.1.1 server and mostly Solaris clients for backup, server is connected with clients via LAN fibre optics and backup storage Dell EMC Data Domain 2500 is mounted via NFS to our NetBackup server also fiber optics. Our issue manifests as two specific policies interleave and the first that is run looses its backup speed and doesn't achieve max potential speed thus backup time of policy that usually finishes in 20 hours lasts around 30 hours. How could we configure client or server settings that when one of the affected policies finishes other regains max potential speed? We have done server tuning as recommended by backup storage vendor as this: ----------------------------------------------------------------------------------------------------- ✔Include the following lines in /etc/system for TCP: set ndd:tcp_wscale_always=1 set ndd:tcp_tstamp_if_wscale=1 set ndd:tcp_max_buf=16777216 set ndd:tcp_cwnd_max=8388608 set ndd:tcp_xmit_hiwat=2097152 set ndd:tcp_recv_hiwat=2097152 for NFS: set nfs:nfs3_nra=16 set nfs:nfs3_max_transfer_size=1048576 set nfs:nfs3_bsize=1048576 set nfs:nfs3_max_threads=256 set rpcmod:clnt_max_conns=64 ✔Add the NFS client mount options "rsize=1048576,wsize=1048576" ✔NFS patch 147268-01 or kernel patch 147440-05 (or later) is installed for Solaris. ---------------------------------------------------------------------------------------------------------------- Changes were done on the media server of NetBackup as we had some troubles with policies speed after that speeds were better but we are still observing before mentioned problems with those two policies when they interleave and the backup speeds in my opinion are not recovering quicky enough when one of those backup policies finishes. Should we make reccomended changes on NetBackup clients also so backup speeds would recover more quickly? TLDR: We can reschedule policies with little effort but how to configure them to achieve maximum speed in less time.1.5KViews0likes4CommentsCan't fix error 2106 Disk Storage Server is down
Hello, Tried calling Veritas support on this matter but alas 7.6 is EOSL... We are backing up to Data Domains using SLPs. In an effort to access the Data Domains, an admin tried to login using the boost account and locked it. I have since re-enabled the account which I thought was the cause of the 2106 errors, but I am still getting them. nbdevquery -liststs -stype DataDomain -U shows the storage servers are down I've tried to change the state using nbdevconfig -changestate, but they still show "down" status. I've also deleted/recreated the boost account on the DDs, and did a tpconfig -update , but I can't get the storage server to come up. Not sure which logs I need to look at to resolve this issue.
