max directory depth and max dir size
by Nicholas Bernstein 02 Mar '12

02 Mar '12

Maybe I'm just being an idiot, but I couldn't seem to find best practices that describe max directory depth and size. I know anecdotally directories shouldn't be larger than 10mb (the directory itself, not the contents) but I can't seem to find an official best practice guide that has these. Can anyone point me to the right doc? Thanks in advance, Nick

backing up a small toaster
by Tom Yates 02 Mar '12

02 Mar '12

Is there anyone out there backing up a toaster *not* using a commercial NDMP-compliant product (eg, Netbackup)? How do you do it? Do I have any options besides (a) direct-attach a dedicated tape drive or (b) commercial NDMP-enabled software, which will enable me to get both UNIX-specific information and CIFS-specific information onto tape safely? Thanks for any light anyone can shed. -- Tom Yates - http://www.teaparty.net

snapshot bolus after re-enabling de-dup
by Fletcher Cocquyt 01 Mar '12

01 Mar '12

We re-enabled dedup on one of our volumes yesterday and observed the 'df-sh' savings go from 20% to 37% (yay!) but the volume usage jumped up snap list revealed a big delta from our usual nightly snapshot delta: > snap list vm65net Volume vm65net working... %/used %/total date name ---------- ---------- ------------ -------- 0% ( 0%) 0% ( 0%) Mar 01 13:47 irt-na03(1573989836)_vm65net.450 (snapmirror) 37% (37%) 27% (27%) Mar 01 00:00 nightly.0 39% ( 4%) 29% ( 2%) Feb 29 00:00 nightly.1 41% ( 5%) 32% ( 2%) Feb 28 00:00 nightly.2 42% ( 4%) 33% ( 2%) Feb 27 00:01 nightly.3 43% ( 4%) 35% ( 2%) Feb 26 00:00 nightly.4 44% ( 4%) 37% ( 2%) Feb 25 00:00 nightly.5 45% ( 4%) 39% ( 2%) Feb 24 00:00 nightly.6 Is this expected behavior? (when I noted these observations I was asked "doesn't dedup work on the snapshots too?") thanks Fletcher
