Sorry you can't believe me, maybe I've made a mistake. Let me check in case I don't know what I'm talking about.
Oh no, I was right, it was 2.5 seconds. My Linux system has 8Gb of memory and the 1Gb file fits easily in it. Because the output was to /dev/null there was no disc needed for output. Hence, all memory based. And only 2.5 seconds. As it is likely the backup time was all down to disc I/O as I'd explained in the first email, then doing multiple backups in parallel will only work of the original jBASE files are split across 2 or more discs -- if you use parallel backups on a single spindle, it will most likely take longer as it will cause even more disc head movement. > > I can't believe the backup of 1GB file in 2.5 seconds on linux or any > other system. possibly in the memory only but usually you can't keep > the whole database in the memory. > > however, to speed up your backup and compress it you can use: > tar -cf - bnk | gzip -1 > filename.tar.gz > > if you need to make it even faster then you can do it in parallel, > several processes will do specific portion of the files within your > bnk directory. > > jaro > > On Jan 20, 1:03 pm, jawwi <[email protected]> wrote: > > Dear All, > > > > We are using jbackup for backing up data files through the following > > commands, > > > > find bnk -print | jbackup -S/home/itops2/stats -f/temenos/backups/ > > jbkp-17112009 -v 2> /home/itop > > s2/Aviion_backup_log > > > > jbackup is taking too long almost 3 hours to backup the entire data > > files which is 72 GB in size. > > > > Is there any method or procedure or switch thats speed up the process > > and also compress the backup file > > > > Stats: > > > > OS : Hp-UX 11i V2 > > DB : JBASE 5.0.16 > > > > Many Thanks in advance. > -- Please read the posting guidelines at: http://groups.google.com/group/jBASE/web/Posting%20Guidelines IMPORTANT: Type T24: at the start of the subject line for questions specific to Globus/T24 To post, send email to [email protected] To unsubscribe, send email to [email protected] For more options, visit this group at http://groups.google.com/group/jBASE?hl=en
