BKF compression algorithm
I m using compression in my bkf file and some of data is compressed and some are not.The shown screen-shot is compressed data of jpg file, so can anyone help me to tell which format so i used to crop the bkf file data of image file. becausehttp://laytongraphics.com/mtf/MTF_100a.PDFin this link compressed block start from FH block and also please tell me where to find a algoritm to decompress this data
Backup to Disk with Compression enabled is very slow ... any tuning options?
Hi, my backup is stable for the past month and i would like to enable compression for the backup to disc jobs. For most normal backup2disc jobs (Hyper-V, Exchange, SQL) the job rate ist about 28-34GB/min. If i enable compression for the same job, it slows down to 4-5GB/min. Where is the bottleneck, is it the Host or the Client System? Is there any option for tuning the compression method or the number of CPU´s that are used for compression? Thanks
Tape Capacity Exceeded When It Shouldn't Be
Hi, Having an issue with Backup Exec 15 where the backup job is exceeding tape capacity, but I don't know why. Each week we have a full backup of our data and system states. As shown in the attachments, this comes to about 4.85TB of space required. I have 4 LTO5 tapes in the unit allocated. These have a base capacity of 5.52TB with no compression. Yet, when the job runs it completely fills those tapes and I have to routinely add another spare tape into the mix, an LTO4. Even that almost gets filled up. Even without compression (which also isn't happening but I can't explain why) I should have more than enough space on the 4 x LTO5 tapes, yet it fills them up and still needs more. I should also mention, the tapes are put into scratch state before the job starts, there is no appending, only overwrite of blank tapes. Can anyone suggest why this might be happening or what I can do to troubleshoot? I receive no relevent errors or warnings which would explain this. Thank you.
