About Pure Disk
Hi All, Kindly let me know the following few questions about pure disk. 1)what is pure disk? 2)About pure disk architecture? 3)About pure disk deduplication? 4)About pure disk web user interface? 5)Can i know the role of vssadminlist writers related to system state backup failures in pure disk.Solved3.8KViews3likes2Comments
Netbackup Appliances 5230 with PureDisk: How many streams?
Hi all, We recently migrated to Netbackup Appliances running Netbackup 7.6.0.1 (Appliance version 2.6.0.1 ) We are running 2 appliances per site, each site is its own NBU domain (We use AIR to replicate). Each appliance is configured with a 70TB PureDisk volume. We are quite new to PureDisk that is running on these systems, but at this moment they are limited to 80 streams maximum in the diskpool object (Which seems pretty low to me) At the moment we are running out of resources due to this maximum that has been set. What is the maximum streamcount a 5230 Appliance PureDisk can safely handle? Note that we are using AIR to replicate all our images, but replication is being done during the day, not during backup times... Any advice is greatly appreciated! Thanks!1KViews1like2Comments
MSDP encryption (ServerOptions=agent_crypt) (or should it be =encrypt)
Hi Forum, Page 30 of the NetBackup Deduplication Guide v7.5 says that... by default MSDP encryption is disabled by default, but they it is recommended by Symantec. Page 70 says that to enable encryption that we need to add "agent_crypt" to "ServerOptions=" in the ContentRouter.cfg file. But looking at the comments in the file: ; [no]agent_crypt : always disable/enable client-side encryption; ; [no]encrypt : always disable/enable encryption; ...indicates that using "agent_crypt" instructs the client-side deduplication agent to encrypt data. At our site we are not implementing client side deduplication so it woudl seem to me that setting :agent_crypt" won't have any effect. My questions are: 1) Is "agent_crypt" really the option to use if what we are trying to achieve is encryption of the post-dedupe blocks on teh MSDP data storage local to teh MSDP media server? 2) What does the "ServerOptions=encrypt" option do, and how is it different to "agent_crypt" ? 3) If we can determine which option really does enable post-dedupe encryption - then does anyone know what the CPU overhead is ? 4) Are there any particular models of CPU (SPARC or Intel or AMD) that implement the encryption/decryption in their hardware instruction sets - i.e. are there any CPUs that are much better suited for use with MSDP encryption ? Thanks, Dave.Solved1.8KViews1like4Comments
How to determine if CR rebasing completed
Hi, I am trying to find a way to find out if the post 6.6.3a PureDisk upgrade Content Router rebasing has completed. It is quite easy to check with the crcontrol if the rebasing option is enabled or disabled at all but I would like to know if the rebasing is still "in progress" or is this "completed". I am aware that this rebasing runs in backgroud and not 24/7 but how to check if all CR entries have been rebased?? Thanks!1.8KViews1like4CommentsNTFS cluster blocking factor for MSDP database and MSDP data volumes?
Hi Forum - I've read elsewhere that is is recommended to format the NFTS volumes that will be used to house the MSDP database and MSDP data with a cluster size of 64 KB (i.e. 128 traditional 512 byte sectors). However if if look at a slightly populated MSDP server, I see most files are less than 64 KB. Does anyone have an opinion on this? Top folders with files... F:\MSDP_Data\history\dataobjects 12 F:\MSDP_Data\history\errors 12 F:\MSDP_Data\history\retention 12 F:\MSDP_Data\history\segments 12 F:\MSDP_Data\history\tasks 12 F:\MSDP_Data\history\tlogs 12 F:\MSDP_Data\log\pddb 43 F:\MSDP_Data\queue 83 F:\MSDP_Data\data 26,205 F:\MSDP_Data\processed 103,610 Total = 130119 Table of file sizes... = 0 75 > 0 29,708 > 4 28,285 > 8 22,436 > 16 12,058 > 32 4,585 > 64 18,802 > 1,024 879 > 10,240 836 > 102,400 220 > 204,800 12,118 > 409,600 108 > 1,024,000 9 Total = 1301191.1KViews1like4CommentsPuredisk 6.6 backup taking very long to complete daily backups.
Hi, need some advise from our Puredisk gurus. Some of our files servers at our remote sites are not completing their daily backups within 24 hour windows and exceeding it ... sometimes may take 3 or 4 days to complete all the backup jobs. Each server have 2.4 - 7.4 total million files and we tried splitting them to a number of smaller jobs (1.5 mil files/600GB - 11.5TB data) to try to get the jobs completed but each job still takes 8 to 10 hours to complete. A typical profile would be Server/backup job "Server ABC (Home Profile folder)" Backup time duration 10.5 hr unique file backed up 7305 File selected on source (K) 1392.268 Total Data size on source (GB) 627.85 Modified (GB) 124.26 Data Change rate 19.79% (modified/total data size*100) Data retention is 45 days. These servers are back up through WAN to a DataCenter and bandwidth does not seem to be the contraint as WAN utilisation lower than 40% during backups. Is there any limits / factors that determines PureDisk backup speed ? I can't seem to find any documents that provides such specifics. Any suggestions or comments ? Would a local puredisk server help ?1.1KViews1like4Comments
NetBackup PureDisk Pool - Segments folder
Hi all, We have a PureDisk pool which fills up rather quickly. On inspection there is a Segments folder (\history\segments) on the PureDisk media server which has over 100GB of data. I haven't been able to find much information on what the data is used for, or if I can safely move or delete the data. Is anyone able to shed some light on this? Thanks!662Views1like2Comments
