Incremental backups?
So I thought I'd get a head start for next week -
I have a low-power Linux box that has a few samba shares mounted, and
limited hard disk space. This box is connected to a tape library via
SCSI card.
I want to find the best way to create a full, then incremental backup of
the samba mounts, directly to tape. Some of the samba mounts are
appliances that cannot run any special

Help with dump/restore
So I recently installed an Overland Arcvault 12 tape library on a server
to back up /var/log/ and /home. The server is an out-of-box RHEL 5
install, with all packages selected, in an isolated lan, with no package
updates. Also, this is a live server that cannot be brought down for
backups, and some files may be actively in use during the dump - just
gotta live with it.
Since I know EL5 and

Backing up remote system
I have an Overland Arcvault tape library, a CentOS 5 box, a Windows XP
system, and RAID box that supports NFS and CIFS.
The RAID box is remotely located and acts as central file storage.
I might normally use dump to perform backups, but as was learned here, and
on dump's man page, dump doesn't support remote file systems such as NFS
or CIFS.
So, for now, I've connected the

Overland Arcvault 12 and sequential/random settings
My unit's firmware: library 05.03, tape d22h, shows the device as set to
random mode. But mtx -f /dev/st0 status gives an error that google says
the device is in sequential mode. dmesg|grep -i hp does reflect CentOS
thinks the device is a sequential unit.
I've tried this with Fedora 8, too, and both show the same, so it is
either an issue with CentOS/Fedora RPMs, or the version of

Command to get tape capacity status?
I have an Overland tape library connected, via SCSI card, to an
out-of-box, full install of C5 install on an old PC.
I have a script that uses tar to archive data to tape and mtx to change
tapes. What I don't know, if possible, is to obtain the status of how
much tape is left in the drive. If I get a write failure, I'd like to
know if the tape is bad or has run out of space.

Timing a command
I want to keep track of how long a task is running. Thinking it wouldn't
take that long, I opted not to run time before it. The fact that it is
taking a long time, if I revisit the machine in the morning, what would be
the best way to find out what time it ended?
In this case, I'm using mt to erase an lto3 tape - sudo mt -f /dev/st0
erase. But I'd like to use the knowledge from

Problems with LTO-3 and U320 on Centos 4.4
I am currently testing an Overland Tape storage unit with a LTO-3 drive
on CentOS 4.4. After a random amount of time but usually when we have
backed up about 0.5-1TB we get scsi errors which cause the backup to
fail. I have rebuilt the box with Solaris 10 x86 and Windoze to prove
the hardware and have successfully backed up over 3TB on each OS without
error.
Can anyone offer advice on how to find

Daily snapshots as replacement for incremental backups
Hello,
I have a situation where a zfs file server holding lots of graphic files cannot be backed up daily with a full backup.
My idea was initially to run a full backup on Sunday through the lto library on more dedicated tapes, then have an incremental backup run on daily tapes.
Brainstorming on this, led me to the idea that I could actually stop thinking about incremental backups (that may always

rsync followup - what did I run?
Many people have wondered what my rsync syntax was -
[as root]: rsync -av /path/to/source me at remote-host:/path/to/dest
I'll be adjusting it to adapt to perform incrementals, probably with --update.
So, just need to learn why some of the .dotfiles, and other unknown
files (unless I ran a diff) didn't successfully copy over.
Thanks.

Tape drive recommendations
Hello all.
I have 15 or so CentOS servers (now v4.4, I will upgrade them all to
5 when it comes out) and a few windows machines. I am looking to
implement a network backup solution using Amanda.
I will be backing up 200 gig or so to start, but that will grow.
Does anyone have any recommendations on tape drives that will work
"out of the box" with CentOS?
Thanks,
Joe

rsync incremental backup
Hi,
Presently I have the latest full backup in a 'current' directory and 30
day incrementals in 'YYYY-MM-DD' format directories. Without changing
that directory structure I'd like the 'YYYY-DD-MM' directories to
contain the full system hardlinked (when applicable) to 'current'.
What rsync command-line options could provide me with this?
Thanks,

first attempt of pvscai backend driver port to pvops
Attached is my first attempt at getting the backend pvscsi driver
(scsiback) working under the latest pvops kernel. I have tested it with
the scsi frontend driver in gplpv, and have restored about 20GB of data
from a HP LTO3 tape drive successfully, so it appears to be working
fine.
There are quite a few changes compared to the version in 2.6.18. The
main change is that I get the vaddr for each

Dump on remote filesystems?
I have a couple C5 systems I want to back up. My plan is to, one way or
another, back them up to a C5 machine in my office. I have samba
installed on the systems to back up, the machines are mounted on the
system in my office, and a tape library hanging of the system in my
office.
I was hoping to perform a simple /sbin/dump of the remote systems. I put

Cronjob script with date stamp?
I have a cron job that calls a shell script - the script invokes dump.
I'd like to do two things:
- Have the script dump the results of the job to a text file. I tried
this with /path/to/dump my switches -v >> /home/me/dump.log
But that just produced an empty file.
- Have the dump file be date-stamped with the date it was executed. Right
now, I manually edit the script to change

Help with backups
I've got a Redhat 5 server running Samba, and two dualboot CentOS 5
workstations.
Until we get a better backup strategy, I'm backing up the workstations to the
server via mounting a shared samba drive to /mnt.
Trying tar cvf /mnt/samba_share/backup.tar /* eventually yields backing up
/mnt, which produces an unwanted loop, including /mnt/samba_share
I looked at tar with --exclude /mnt

no true incrementals with rsync?
for example's sake:
With traditional backup systems, you keep a base (full backup, let's say
every 30 days), then build incrementals on top of that, eg. (what has
changed since the base).
So, to restore, you copy over your base, then copy each incremental over the
base to rebuild up to the latest snapshot. (*copying new incrementals files
over older base files*)
With rsync, (using

LVM, usb drives, Active Directory
I have a client with a handful of USB drives connected to a CentOS
box. I am charged with binding the USB drives together into a single
LVM for a cheap storage data pool (10 x 1 TB usb drives = 10 TB cheap
storage in a single mount point).
The next fun piece is how to incorporate that storage space into an
existing Active Directory structure to apply AD acls for limited
access.
