Re: [zfs-discuss] ZFS versus VxFS as file system inside Netbackup 6.0 DSSU

2008-02-13 Thread Sri Sudarsan
Selim, Symantec does support ZFS as DSSU targets. I've also seen a SUN white paper outlining the use of Thumper (Sun X4500) as a NB 6.5 media server, where the best practice was to to configure multiple NB disk storage units to use a distinct ZFS file system. In this case, all the ZFS file sy

AFAIK , nbu does of estimated the size of backup prior starting the job. as the backup job is split in fixed-size segments , if a segment does not fit, it will try to backup into another disk or will wait for more space On Jan 15, 2008 8:42 PM, Paul Kraus <[EMAIL PROTECTED]> wrote: > On 1/15/08, S

with zfs you can compress data on disk ...that is a grat advantage when doing backup to disk also, for DSSU you need to multiply number of filesystem (1 fs per stu), the advantage of zfs is that you don't need to fix the size of the fs upfront (the space is shared among all the fs) s- On Jan 10,
