Hello everyone, using bacula 5.0.3. on a x64 SuSE we do our backups to disk, keep them there for 2 months und then migrate them to tape. Migration is done to LTO-5 Tapes on a Dell TL-4000 changer with a single drive. When installing the library I didn't care too much about performance so I didn't specify any block-size expressions in the device resource (as suggestet in the manual). We do our migrations with a 50-70 MB/s data-rate which is OK for us but quite low for LTO-5. Our hdd-subsystem can deliver data-rates of obout 200 MB/s (testet with different performance-tools). To improve performance of the tape drive I'd like to heighten the maximum block size.
My question is: Will bacula be able to read the already written tapes after the block-size-change? Any advice would save me a lot of testing time. Thanks for your help. -- Mit besten Grüßen / Kind Regards Jens-Uwe Mohn IT System Management g/d/p Marktanalysen GmbH Ein Unternehmen der Forschungsgruppe g/d/p Richardstr. 18 D-22081 Hamburg Fon: +49 (0)40 / 29876-170 Fax: +49 (0)40 / 29876-127 m...@gdp-group.com www.gdp-group.com Sitz der Gesellschaft ist Hamburg, Handelsregister Hamburg, HRB 37830 Geschäftsführer: Christa Braaß, Volker Rohweder, Clemens Steckner ------------------------------------------------------------------------------------------------------------- This e-mail may contain confidential and/or privileged information.
