Yes, an error in a gzipped tar will mean you lose the lot. However it's fine to gzip each file and then tar all those together.

[SLUG] email server errors
Hi Slugs, We are getting lots of "unrouteable mail domain" messages both from internal messages going out and we are hearing from others emailing us that emails have been sent but bounced back from us. (Even this message bounced back once) I'm looking into "frozen messages" errors from the exim logs. I suspect the email server, which is currently running debian and exim/qpopper, is on a very underpowered machine. (pentium 90 64Mb for 350-400 users.) I'm looking at setting up a more powerful PC running (most likely) Mandrake 8.2. Just looking for clues as to how you would migrate over to a new box without interrupting the email flow. Clients are windows boxes with outlook clients and a hard coded ip address for the debian mail server. Just looking for pointers in the right direction and any gotcha's that anyone has had.

Re: [SLUG] tar backups to tape
You can try using tar with the I flag - that will use bzip2 compression. However, if you value your data - NEVER use compression on a backup - should part (ie one bit) of the backup be corrupted (common with tapes) the whole archive is useless.

Re: [SLUG] tar backups to tape
Yes, Arkeia claims it's using 1.2 compression (with LZ1 I think). What sort of compression could I use with tar to achieve similar results to Arkeia? I tried compress & gzip and it went just as slow What's the switch to play with the blocking factor? Also, I tried setting the block size to 2048 to see if it speeds it up and it didn't help at all.. It's an Ecrix VXA-1 Tape Drive on a Adaptec 2940 SCSI Card. >From dmesg: scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.4 aic7870: Single Channel A, SCSI Id=7, 16/253 SCBs Vendor: ECRIX Model: VXA-1 Rev: 2848 Type: Sequential-Access ANSI SCSI revision: 02 (scsi0:A:4): 10.000MB/s transfers (10.000MHz, offset 15) st: Version 20011103, bufsize 32768, wrt 30720, max init. bufs 4, s/g segs 16 Attached scsi tape st0 at scsi0, channel 0, id 4, lun 0 Arkeia *is* doing a full backup.

[SLUG] Sendmail woes
Hi all, In the final stages of recovering my system. The final hurdle is that mail cannot be received, although it can be sent. The following is in the rejected mail: - The following addresses had permanent fatal errors - <[EMAIL PROTECTED]> (reason: can't create (user) output file) - Transcript of session follows - procmail: Lock failure on "/var/spool/mail/sbryan.lock" procmail: Error while writing to "/var/spool/mail/sbryan" 550 5.0.0 <[EMAIL PROTECTED]>... Can't create output The setup is RH7.2 Sendmail 8.11 (came on the CD) The directories /var/spool/mail and /var/spool/mqueue are both symlinks to directories on /var/auc which is where the new HDD is mounted, twas like that before. This is the permissions and settings on the real directories: drwxrwxr-x2 root mail 4096 Apr 10 12:16 mail drwxrwxr-x2 root mail16384 Apr 10 11:13 mailold drwxr-xr-x2 root mail40960 Apr 10 12:16 mqueue The symlinks are: lrwxrwxrwx1 root mail 19 Apr 10 11:39 mail -> /var/auc/spool/mail lrwxrwxrwx1 root mail 21 Apr 10 12:18 mqueue -> /var/auc/spool/mqueue and chmod has no effect on them. Sendmail is running as root and listening on port 25 FOund this on the net (googling): Lock failure on "x" Can only occur if you specify some real weird (and illegal) lockfilenames or if the lockfile could not be created because of insufficient permissions or nonexistent subdirectories. So assume it is permissions, have tried 777 on the mail directory but same result.

Re: [SLUG] tar backups to tape
If Arkeia is backing up at 180Mb/min then this is equivalent to 3Mb/s, 2-3x faster than tar. Is Arkeia using compression ??? It is possible, and that may be why it is reporting faster transfer times to tape than tar is. You can also play with the tar blocking factor - it will depend on the network transfer speed. The other thing is, what sort of tape drive are you using, what sort of controller ? What is the maximum rated transfer rate for the tape drive ? Another stupid question - is Arkeia doing a FULL backup or an incremental ? From the look of this, you network is probably not the bottleneck. I would also suggest you take a look at ctar (do a google search). It costs money but you can install a trial version and compare that.

Re: [SLUG] What files/directories to backup in RH ?
I would just backup your /home/ directory, and maybe /etc if you have done a lot of config on the thing, (like a webserver etc..). I personally have my /home dir mounted by nfs (thinking about coda), and stored on my home server. If any machine other than the server goes down it's just a matter of: Format, and then, re-install, Do da, do da. I just tell rh7.2 to use nis as i am installing it, and then give it the mount details for nfs, and run ximian gnome on it (I also mount /var/cache/redcarpet with nfs). Ta da, im done. I then just backup the /etc and /home dir on the server. I have had the server go down only once on a (noisy) Seagate 30Gb 7200RPM. Got a 40Gb WD, reinstalled RH7.2 copied over the backups (and did some minor tweaking I had been meaning to do for ages), and was done. Dats my .02c worth.

Hi Rajnish What I would do is backup /etc, /home, /usr and /var.

Re: [SLUG] tar backups to tape
Hi Matt I took your advice and tried backing up / on the backup server (excluding /dev and /proc of course) to tape and tar reported: Total bytes written: 1427005440 (1.3GB, 1.2MB/s) It took about 15 minutes to complete this. My fileserver has about 30GB worth of data. So, it would take approximately 6 hours to complete using tar. This is just for the fileserver. It's actually taking a lot longer than 6 hours (since it has to come over through the network) but anyway... using Arkeia, I can backup the fileserver AND mail server (which is only an extra 3 or so gigs) in 2 hours and 20 minutes. Arkeia reports the speed was 180MB/min. There's something I'm doing wrong here and Arkeia is doing right because I don't understand how Arkeia can backup ~160 faster than tar. Any further ideas??

Re: [SLUG] tar backups to tape
Generally, tapes are streaming, so it is possible that if the transfer rate across the network is slow then more tape may be required for the same amount of data. Really - you need to determine the bottleneck - can you tar from one machine to the HDD on another and see how long it takes - and then locally tar this data to the tape drive. That should give you some good ideas of where the performance bottleneck is.

Re: [SLUG] Redhat 7.2 crashes my computer
Thanks ya all for ya effort in helping me. I found that editing the makefile in the tld of the kernel code tree and changing the two references of gcc to gcc3 works well. And just deleting the gcc file and replacing it with a symlink to gcc3 also works but that messes up the rpm system thing a bit. I have had the machine up for a day so far with linux-2.4.18 compiled under gcc3, and no crash yet. I am still using gnome, for now as a matter of elimination though. If it crashes again I will go to KDE3, (and start a lot of flaming :-). Regards, and thanks for your help again.

Simon, When you have a moment, try using "mt" to access the tape - at least that will tell you if the SCSI interface is accepting commands; mt -f /dev/sto status (or rewind, or erase, etc) Jon -- SLUG - Sydney Linux User Group Mailing List - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
