similar to: using rsync for incremental raw disk backup?

Hello, Andrew Trigdell's original rsync paper (actually thesis) discussed the idea of using rsync to make incremental tape backups based not on whole files but rather parts of files. Sadly, this functionality is not actually present in the rsync program. I'd like to explore adding this ability. There are basically three things that need to be done to enable efficient (partial-file)

The guestfish prepared disks (-N option) all defaulted to 100M. This has always been too small for btrfs (so for example ‘-N fs:btrfs’ has failed for a long time), and can be too small for LVs with new LVM2 / kernel >= 4.16. This changes the default from 100M to 1G. The beginning of the 1.39 branch seems like a good time to make this change. --- fish/guestfish.pod | 14 +++++++-------

I'm pulling my hair out trying to setup a mirrored logical volume. lvconvert tells me I don't have enough free space, even though I have hundreds of gigabytes free on both physical volumes. Command: lvconvert -m1 /dev/vg1/iscsi_deeds_data Insufficient suitable allocatable extents for logical volume : 10240 more required Any ideas? Thanks!, Gordon Here's the output from the

Hi People I just updated a CentOS 5.2 Server that is a Guest inside VMware ESX 3.50 Server using "yum update". As far as I can tell the only three packages were updated Jul 24 16:37:49 Updated: php-common - 5.1.6-20.el5_2.1.i386 Jul 24 16:37:50 Updated: php-cli - 5.1.6-20.el5_2.1.i386 Jul 24 16:37:50 Updated: php - 5.1.6-20.el5_2.1.i386 But when I rebooted the Server one of my

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

Hai, I use following steps for LV backup. * lvcreate -L 5G -s -n lv_snapshot /dev/VG_XenStorage-7b010600-3920-5526-b3ec-6f7b0f610f3c/VHD-a2db885c-9ad0-46c3-b2c3-a30cb71d83f8 lv_snapshot created* This command worked properly Then issue kpartx command kpartx -av

Hi list. I am dealing with DRBD (+GFS as its DLM). GFS configuration needs a CLVMD configuration. So, after syncronized my (two) /dev/drbd0 block devices, I start the clvmd service and try to create a clustered logical volume. I get this: On "alice": [root at alice ~]# pvcreate /dev/drbd0 Physical volume "/dev/drbd0" successfully created [root at alice ~]# vgcreate

I need to recommend some backup options for a web server running CentOS 4.1. The client prefers using a tape drive as their backup device and has access to safe offsite storage. I was thinking of system backups weekly and differential backups nightly but don't know what software to recommend for the differential b/u's. For full backups I can just schedule a tar and compress using

We've recently migrated my entire University including faculty and staff from Novell to Samba. There's typically 700+ clients connected to the samba server at any given time and thus far there are about 400GB of client's files on the server. Basically every Microsoft Windows user generated file (Word, Excel, whatever) of the entire University gets stored on my Samba server. Obviously

Hi All. Currently I am trying to change a logical volume from linear to stripped because I would like to have a better write throughput. I would like to perform this change "live" without stopping access to this lv. I have found two interesting examples: http://community.hpe.com/t5/System-Administration/Need-to-move-the-data-from-Linear-LV-to-stripped-LV-on-RHEL-5-7/td-p/6134323

We're using RMAN to back up our 9.2 RAC database to an OCFS v1 volume. We have an existing shell script that we use for copying files from disk to tape via tar, one file at a time. (Don't ask why. It's a legacy script. Long story.) We're tweaking this script to use --o_direct when tarring the file to tape and that seems to be working fine: # tape device is /dev/nst0 $ tar

Hi We use AoE disks for some of our systems. Currently, a 15.65Tb filesystem we have is full, I then extended the LVM by a further 4Tb but resize4fs could not handle a filesystem over 16Tb (CentOS 5.5). I then reduced the lvm by the same amount, and attempted to create a new LV, but get this error message in the process lvcreate -v -ndata2 -L2T -t aoe Test mode: Metadata will NOT be updated.

Hi all, I'm having problems to create/resize an lv up to 1T (well I can't reach 300G), my system is a CentOS 5.1 x86_64 on a Dell 2950 with 6x500G SATA (RAID5 to aprox. 2.5T) [root at Mugello ~]# fdisk -l Disk /dev/sda: 2497.7 GB, 2497791918080 bytes 255 heads, 63 sectors/track, 303672 cylinders Units = cilindros of 16065 * 512 = 8225280 bytes Dispositivo Boot Start

BackupPC version 1.03 has been released on SourceForge, see http://backuppc.sourceforge.net. BackupPC a high-performance perl-based package for backing up Linux and WinXX PCs and laptops to a server's disk. BackupPC is highly configurable and easy to install and maintain. It uses Samba's smbclient to extract files from clients, and uses Samba on linux clients to serve up shares (no

Dear all, given a DVD drive and DAT Tape Drive, and using Solaris 10 U7 (5/09), how can we plan for a total backup of ZFS root disk and procedure to recover that? Previously using UFS, we just need to use boot from Solaris OS DVD media, also using ufsdump, ufsrestore and installboot. Anybody can point me on how to achieve the same thing when the whole system disk are busted? Thanks in

Recently we have started using Arc serve backup. The Arc server and the tape library are connected to a Windows 2000 server machine and the data files are stored on many Samba file servers. I have Linux Client Agents installed on all Linux Machine. Now the problem is that when Arc Serve backup the file it always backup the full files irrespective of setting for a differential backup. I think

CentOS 7 for everything I am probably never using lvm again. I have never not once actually benefited from its capabilities but this is probably the third or fourth time it has gotten in my way. Issue is that I use the tools so rarely that I can't recall what needs to be done to properly mount the drives on another system and finding that info on the web is becoming more difficult as the
