Executive summary
This paper provides informa t ion a bout how to set up the Dell DR Series Ded u plicati on A p p liance as a
backup target device for Del l NetVa ult (NVBU®) Backup™ software using RDA technology. Th is paper
is a quick r eference g u id e and does not include all D R Series Ded u p licati on Appliance deployment best
practices.
Abbreviations and Mea ni ng :
RDA : Rapid Data Access, D ell propri etary technology for fa s ter data access.
Dedupe Backup : In this mode D ed u p lication is done on th e Client an d then the ded up licated pa ck ets are
sent to DR Series Dedu plicati on A p p liance.
Passthrough Backup : In this mode Deduplication is done on DR Series Deduplication A p p liance after
data is transferred from Clients and backup media server.

3 Configure Backup Job on NVBU
There ar e two tra nsp ort mode s f or backin g up data over RDA – Optimized / Dedup and Passthrough.
Optimized backup does source side dedupe on the NVBU clients. The Passthrough mode does tar g et
side dedupe, that is on the DR Series Dedupl ication Ap pl iance.
The default mode for each cli ent is decided ba sed on the number of CPU cores in th e client machine
and whether the architecture is 32-bit or 64 -bi t. In general there is no need to change mode. But in case
you want to chang e th e mode, it can be done by settin g RDA mode in DR Series Ded u pl ication
Appliance com man d prompt or th rough GUI.
CLI: Open ssh session to DR Seri es Dedupli cation Appl iance and run ‘rda --update_client --name
<hostname of client> --mode <dedupe/passthrough>
GUI: Bro wse t o C lients pa g e, s elect RDA ta b. The list of cli ents th a t have active connections are
shown. Select th e client for which you want to chang e th e mode. On top ri ght side, click on Update
Client link. Sele c t req uire d mode from th e drop down box and Su bmit.
NOTE: Except for NVBU’s file system plug-in, all the other pl ug -ins are 32 Bit binaries on
Windows (64-bit or 32-bit versions). There is a known iss u e beca use of which optim ized back-ups
13 Settin g up RDA Backup to Dell™ DR4x00 Disk Backup Applianc e on Dell™ NetVault
with 32 bit plug-ins provide less per formance than pass thr ou g h back-ups. It is recommended to stick
to the d efa u lt that DR ch ose to use rath er th an forcing the mode to be optimized even if the clien t h as
more horse power. N VBU clie nt running on a 6 4-bit Linux machine has 64-bit plug ins.
1. On NVBU console, select Backup. On Selections tab, choos e the data s et n eed s to be backed up.
2. On Backup Options t ab, choose appr opria te options .
14 Settin g up RDA Backup to Dell™ DR4x00 Disk Backup Applianc e on Dell™ NetVault
NOTE: Before doing any Incremental/Differential backup, make sure you have a Full backup run
with same ‘Backup Selection Set’.
NOTE: NVBU’s “consolidated incremental plugin” might not be very efficient with RDA device, as
optimized synthetic backups are not yet supported with NVBU RDA. This works functionally, but
performance might suffer.
3. On Schedule tab, configure t he bac kup job sche dule.

4. On Target tab, choose t he RDA d evi ce created in step 2.
5. On Advanced ta b, make select ions on the advanced backup opti ons.
16 Settin g up RDA Backup to Dell™ DR4x00 Disk Backup Applianc e on Dell™ NetVault
Selecting ‘Cre ate Sec ondar y Copy’:
If you want to Duplicate/Replicate the backup Image after the backup is done, select Create
Secondary copy option . Th en select target and sou rce devices.
To select target d evice navi gate to: Advanced opti ons -> Enable ‘Create Secondary Copy’ -> Using
target Set -> Manag e -> Select Device
To select source device: Using Source Set -> Manage -> Select Device
Selecting ‘optimized replication’:
17 Settin g up RDA Backup to Dell™ DR4x00 Disk Backup Applianc e on Dell™ NetVault
Select ‘Use optimized replication betwee n devices t hat support this feat ure ’ . Thi s enables
Optimized duplicat ion between s ource and target Cont ainers.
Additional Advance d opti ons:
Encryption: Advanced opti ons -> Enable Encryption. Make sure this is unchecked. Deduplication
savings as well as throughput would be lower if encryption is enabled.
Deduplicati on: Advance d options -> Enable Deduplication. This does not apply when backing-up
to RDA devic es. Leave i t uncheck ed . Refer to NVBU 9. 2 A dm in istrat ors Guide for more detail s .
Network Compression: Advanced options -> Enable Network Compression. This does not apply
when backing-up to RDA device s . Leave it unchecked.
6. Click on Save m enu but ton to save the job.

4 Set Up the DR Series Deduplication Appliance Cleaner
The cleaner will run during idle time. If you workflow does not have a sufficient amount of idle time
on a daily basis then you should consider scheduling the cleaner which will force it to run during that
schedu led tim e.
If necessary you can do the follo wi ng procedure described in the screen shot to force the cleaner to run.
Once al l the backup jobs are setup the DR4x00 cleaner can be schedu led. The DR Ser ies Dedup li cation
Appliance cleaner should run at least 6 hours per week when backup s are not takin g place, generally
after a backup job has completed.
Perfor ming sch ed uled disk sp ace reclamation operations are recommended as a m ethod for recov ering
disk s pa ce from system contain er s in which files were delet ed as a result of deduplication.

Monitor Dedupe,
5 Monitoring Deduplication, Compression and
Performance
After bac kup jobs have completed, the DR Series Deduplica tion Appl iance tracks capacity, storage
savings and throughput on the DR Seri es Ded uplication Appli ance dashboard. This information is
valua bl e in understanding th e benefits the DR Series Deduplication Appliance.
NOTE: Deduplication ratios increase over time; it is not u nc ommon to se e a 2-4x reduction (25-50% total
savings) on the initial backup. As additional full backup jobs complete, the ratios will increase. Backup
jobs with a 12-week retention will average a 15x ratio in most cases.
