fedora 32 man.m.sourcentral.org PARTCLONE(8) Partclone User Manual PARTCLONE(8) NAME partclone − The utility for clone and restore a partition. SYNOPSIS partclone.[fstype] {[−c | −−clone][−r | −−restore][−b | −−dev−to−dev]} {[−s | −−source] source} {[[−o | −−output][−O | −−overwrite]] target} [[−dX | −−debug=X][−−restore_raw_file]] [[−z | −−buffer_size][−N | −−ncurses]] [[−q | −−quiet][−f | −−UI−fresh]] [[−F | −−force][−I | −−ignore_fschk]] [[−−ignore_crc][−X | −−dialog][−C | −−nocheck]] [[−R | −−rescue][−L | −−logfile] logfile] DESCRIPTION partclone.[fstype] is a part of Partclone project. Partclone provide utilities to backup used blocks and design for higher compatibility of the file system by using existing library,e.g. e2fslibs is used to read the used block of ext2 partition. Partclone supported file system include btrfs, ext2, ext3, ext4, reiserfs, reiser4, xfs and jfs for LINUX. Also support some non−linux operation system, ex: NTFS, FAT and EXFAT(for Windows), HFS plus(APPLE MACOS), UFS2(FreeBSD), VMFS(VMWare Vsphere) and MINIX(MINIX3). All partclone utils could be run likepartclone.[fstype] is very smiliar fsck or mkfs. For example, for backup/restore hfsplus, just run partclone.hfsp File System partclone.[fstype] btrfs partclone.btrfs ext2, ext3, ext4 partclone.[ext2|ext3|ext4] reiserfs 3.5 partclone.reiserfs reiser 4 partclone.reiser4 xfs partclone.xfs ufs | ufs2 partclone.ufs jfs partclone.jfs hfs plusfs partclone.[hfs+|hfsplus] vmfs partclone.vmfs ntfs partclone.ntfs fat12, fat16, fat32 partclone.[fat12|fat16|fat32] exfatpartclone.exfat minix partclone.minix f2fs partclone.f2fs nilfs2 partclone.nilfs2 OPTIONS The program follows the usual GNU command line syntax, with long options starting with twodashes (‘−').

Recommendations for Aligning VMFS Partitions
VMWARE PERFORMANCE STUDY VMware Infrastructure 3 Recommendations for Aligning VMFS Partitions Note: This paper is now considered obsolete. For the latest information on this topic please consult Performance Best Practices for VMware vSphere® 4.0. Partition alignment is a known issue in physical file systems, and its remedy is well documented. The goal of the testing reported in this paper was to validate the assumption that unaligned partitions also impose a penalty when the partition is a VMware Virtual Machine File System (VMware VMFS) partition. This paper lists a summary of the results of our testing, recommendations for VMware VMFS partition alignment, and the steps needed to create aligned VMware VMFS partitions. It covers the following topics: • Executive Summary on page 1 • Recommendations on page 2 • Instructions for VMware VMFS Partition Alignment Using fdisk on page 2 • Instructions for Guest File System Alignment on page 3 • Caveats on page 5 • Background on page 5 • Performance Results on page 8 • Conclusion on page 10 • References on page 10 Executive Summary Our testing validates the assumption that VMware VMFS partitions that align to 64KB track boundaries result in reduced latency and increased throughput. Partition alignment on both physical machines and VMware VMFS partitions prevents performance I/O degradation due to unaligned tracks. Creating VMware VMFS partitions using the Virtual Infrastructure Client (VI Client) that is part of VMware Infrastructure 3 results in a partition table aligned on the 64KB boundary as storage and operating system vendors recommend. Throughput Increase Latency Decrease Min = 2% Average = 12% Min = 7% Average = 10% Max = 62% Max = 33% 1 Recommendations for Aligning VMFS Partitions Note: These recommendations are for block-based storage solutions, not those that are IP- based. -

Disk Cloning Image Cloning
Disk Cloning Image Cloning Clone a disk or partition to a file Best image tools will backup only data sections of the disk Compression is a handy feature Live backups are available but I don't recommend this. Image Cloning FSArchiver 0.23 NTFS, EXT2/3/4, xfs, jfs filesystems support (FAT, HFS & UFS not supported). Compression is fast utilising multiple threads. corrupt image recovery Image Cloning FSArchiver Create a backup $ net-setup eth1 $ mount.cifs //server/public /mnt -o user=<my user> $ time fsarchiver savefs -z 1 -v /mnt/archive_name.fsa /dev/sda1 Restore a backup $ net-setup eth1 $ mount.cifs //server/public /mnt -o user=<my user> Use gparted to format beforehand. $ time fsarchiver restfs -v /mnt/archive_name.fsa id=0,dest=/dev/sda1 Image Cloning Image cloning is a bit of a multi step process Image Cloning FSArchiver Pros Fast Good compression Encryption options Good filesystem support Cons No support for UFS (BSD systems) Two step process to clone a drive. Partition Cloning Clone just part of the disk Partition Cloning Copy just a partition and only the data on that partition. This is the preferred cloning technique. This is what the popular proprietary software packages like 'Ghost' perform. Partition Cloning gparted - http://gparted.sourceforge.net/ Installed as default on Ubuntu & used in it's setup. To use this for cloning a system disk use a live cd. GUI driven Many other abilities. Partition Cloning gparted - http://gparted.sourceforge.net/ Pros Support for EXT4, UFS, HFS, NTFS and some more exotic filesystems like XFS Easy to use Can resize most partitions (no shrinking for UFS). -

Efficient Bare Metal Backup and Restore in Openstack Based Cloud Infrastructure Design, Implementation and Testing of a Prototype Addishiwot Tadesse
Thesis no: MSEE-2016:36 Efficient Bare Metal Backup and Restore in OpenStack Based Cloud Infrastructure Design, Implementation and Testing of a Prototype Addishiwot Tadesse Faculty of Computing Blekinge Institute of Technology SE-371 79 Karlskrona Sweden I This thesis is submitted to the Faculty of Computing at Blekinge Institute of Technology in partial fulfillment of the requirements for the degree of Masters in Electrical Engineering with Emphasis on Telecommunication Systems. The thesis is equivalent to 20 weeks of full time studies. The master thesis research was carried out at Ericsson AB in Göteborg, Sweden. Contact Information: Author: Addishiwot Tadesse E-mail: [email protected] University Supervisor Dragos Ilie(Assistant Professor) [email protected] Department of Communication Systems School of Computing BTH, Karlskrona Ericssson’s Manager Lars Samuelsson [email protected] Göteborg, Sweden Ericssson’s Supervisors: Tony Borg Senior Packet Core Verification Engineer [email protected] Göteborg, Sweden Asgrimur Olafsson Senior Packet Core Solution Engineer [email protected] Göteborg, Sweden II Abstract Cloud computing has shown remarkable growth in recent years due to its concept of computing as a service, thereby, allowing users to offload the infrastructure management costs and tasks to a cloud provider. With the rapid development of these services, data has become the most crucial resource and hence companies start building disaster recovery (DR) systems that are more vital and essential to ensure the reliability and availability of data services in the event of IT infrastructure disasters. The occurrence of an unexpected calamity in a system leading to its disruption is a disaster.
