Can I backup fs containing holding disk?
I'm brand new, so let me first say thank you, this looks like a pretty full-blown backup implementation. Bunch of new user questions: can I put the holding disk on one of the file systems I'm backing up (backing up the tape server host itself)? Does amanda backup the entire filesystem, both the used space and the empty space? Since it uses the fs /dev/ entries, do I need to be concerned about symlinks that cross slices? I'm using a Seagate Scorpion DDS-2 (4G/8G) drive. Should I skip amanda's compression and use the hardware compression? I've been using tar, and I made uncompressed tar files of about 1.8G and 1.2G and used hardware compression to get them to both fit on a 2G/4G tape. But I've added more content, and now the 1.8G file is over 2G, and tar seems to use a signed 32-bit int, so I'm hosed beyond 2G (.tar cannot contain any single file over 2G). So since the tape is a .tar file itself, it was crapping out on the 2G file. Here's what I used to do: /usr/bin/tar -cf /var/spool/backup/ns.tar --exclude /mnt --exclude /dev --exclude /var/tmp --exclude /var/spool/backup --exclude /var/squid --exclude /usr/tmp --exclude /usr/home/smbd/MP3 / Then I'd tar _that_ file (ns.tar) and one other similar tar file from another host onto my tape drive. _That's_ what wouldn't work once ns.tar grew beyond 2G. Sorry to ramble. I think I can dig enough to figure out amanda's exclude mechanism. Do I need to explicitly exclude the directory where amanda is putting the dump images, or will amanda know to do that? How does amanda handle symlinks that cross filesystems? When an excluded directory is a symlink, should I exclude both the physical dir _and_ the logical link, or just the physical dir? Here's what I want to back up. Subtract about 2G from /usr/home for stuff that doesn't have to be backed up, and another 3-3.5G on /usr that doesn't need to be backed up. /var/spool/backup is a symlink to /usr/tmp/backup, and I'm putting my holding files under /var/spool/backup. Hence the question about excluding symlinks, will amanda know to exclude /usr/tmp/backup/dumps because that's where /var/spool/backup/dumps resides? Filesystem Size Used Avail Capacity Mounted on /dev/idad0s1a 124M83M31M73%/ /dev/idad0s1h 9.7G 5.0G 3.9G56%/usr /dev/idad0s1d 4.9G 3.1G 1.4G68%/usr/home /dev/idad0s1e 124M64M50M56%/var /dev/idad0s1g 992M37K 913M 0%/var/spool /dev/idad0s1f 124M73M41M64%/var/tmp Holler if I can confuse this a little more. The evening is still young here on the left coast. Thank you!

Using AManda
hi! I am a beginner here. ACtually i need to backup a NFS mounted file system (only /home) from a linux client/server on to iself or any other linux client's hard disk (sorry no tape drive business!). How shd I configure my amanda-conf for this? And what would be reasonable values for dumpscyle , tapedev,tapechanger? Also the previous mails told me that dump was not recommended for linux?and that one hsd go for tar ? Is that so? i have tar 1.13.17 . Will that be good or do i need to upgrade to 1.13.19 .Also i dont have readline, termcap. Do i also need to install them?

Re: Amanda + solaris
Good morning all, The sgen driver works well on Solaris 8. That fixed my need to roll my own. The only change I needed to recognize the HP C7200-8000 changer was to modify the sgen.conf with the following lines: device-type-config-list="library"; inquiry-config-list="HP", "C7200-8000"; and of course uncomment the: name="sgen" class="scsi" target=0 lun=0; . . . lines. mtx works very well with the changer and the DLT8000 drives. Thanks to Jon LaBadie, Thomas Hepper and Craig Dewick. > On Tue, 23 Apr 2002, Thomas Hepper wrote: > > > Hi, > > On Tue, Apr 23, 2002 at 03:35:34PM +0200, Ryszard Kluza wrote: > > > Hello > > > > > > I have Sun E250 with Solaris 7 > > > > > > Tape library Adic FastStore22 > > > > > > And amanda > > > > > > How I have to configure amanda and solaris to work together, > > > > > > What kind of driver I need to instal on Solaris > > > > I'm not sure if solaris have already the sgen driver.
