EMC E20-598Backup Recovery - Avamar Specialist forStorage AdministratorsEMC E20-598 Dumps Available Here m/e20-598-dumps.htmlEnrolling now you will get access to 237 questions in a unique set of E20598 dumpsQuestion 1For each file that is backed up in an EMC Avamar system, how many total bytes are added to the filecache?Options:A. 20B. 24C. 40D. 44Answer: DExplanation:The most important thing to do on a client with so many files is to make sure that the file cache is sizedappropriately. The file cache is responsible for the vast majority ( 90%) of the performance of the vamarclient. If there's a file cache miss, the client has to go and thrash your disk for a while chunking up a file thatmay already be on the server.So how to tune the file cache size?The file cache starts at 22MB in size and doubles in size each time it grows. Each file on a client will use 44bytes of space in the file cache (two SHA-1 hashes consuming 20 bytes each and 4 bytes of metadata).For25 million files, the client will generate just over 1GB of cache and-large-dataset-with-multiples.htmlQuestion 2The EMC Avamar client needs to backup a file and has performed sticky-byte factoring. This results in om

EMC E20-598- Seven (7) chunks that will compress at 30%- Four (4) that will compress at 23%- Two (2) chunks at 50% compressionHow many chunks will be compressed prior to hashing?Options:A. 4B. 7C. 9D. 13Answer: CExplanation:vamar, has a rather nifty technology called Sticky Byte Factoring which allows it to identify the changedinformation inside a file by breaking the file into variable length objects, this leads to much greater efficiencythan fixed size approaches as changes made early in a fixed length sequence affect all subsequent blocks/chunks/objects/whatever in that sequence. This in turn changes all the fingerprints taken following thechanged data which means you end up with a lot of new blocks/chunks/objects/whatever even if the datareally hasn't changed all that much. Sticky Byte Factoring on the other hand can tell what exactly haschanged, not just that things have changed.Question 3Which hash type represents an individual data chunk processed during an EMC Avamar backup?Options:A. AtomicB. RootC. CompositeD. MetadataAnswer:
