Line 663: − ==== Performance ====+ − − It is hard to predict how much time a backup job needs to complete. It depends on the number of files, the total file size, the file changes since last run, the network speed and not least on the CPU power, disk speed and RAM of the source and backup server. The following table of measured values will give you an idea of what you can expect. − − {| border="1" cellpadding="3" cellspacing=0 − |- − | '''Backup server''' || '''Source server''' || '''Data on source server''' || '''Transferred Data''' || '''Connection''' || '''Compression''' || '''Affa run time''' − |- − | 2x3.2GHz Xeon<br>2 GB RAM, 1.5 TB RAID6 − | 2x3.2GHz Dual Core Xeon<br>4 GB RAM, RAID5, SME 7.1<br>Intranet Web Server + MySQL|| 1.4 GB, 12,000 files|| 300 MB, 16 files || Internet 2 Mbit || yes || 2 minutes − |- − | 2x3.2GHz Xeon<br>2 GB RAM, 1.5 TB RAID6 − | 2x3.2GHz Dual Core Xeon<br>4 GB RAM, RAID5<br>SME 7.1 Mailserver || 43 GB, 410,000 files || 140 MB, 2,700 files || Internet 2 Mbit|| yes || 10 minutes − |- − | 2x2GHz Dual Core Xeon 5130<br>6 GB RAM, 1 TB RAID 5 − | 2x2GHz Dual Core Xeon 5130<br>6 GB RAM, 1 TB RAID 5<br>SME 7.1 File- and Mailserver || 125 GB, 98,000 files || 3,2 GB, 3,000 files || Gbit LAN || no || 25 minutes − |- − | 2x2GHz Dual Core Xeon 5130<br>6 GB RAM, 874 GB RAID 5 − | 2x2GHz Dual Core Xeon 5130<br>6 GB RAM, 1 TB RAID 5<br>SME 7.1 File- and Mailserver || 125 GB, 98,000 files || 3.5 GB, 2000 files || Internet 2 Mbit || yes || 17 minutes − |- − | 2x800MHz Pentium 3<br>1 GB RAM, 300 GB RAID1 − | 2x2.8GHz Xeon,<br> 1GB RAM, 140 GB RAID5<br>SME 7.1 File- and Mailserver || 39 GB, 370,000 files || 12 GB, 4,000 files || 100Mbit LAN || no || 52 minutes − |- − | 1xP4 2.4GHz<br>256 MB RAM<br>SME 7.1 − | 2xP4 1GHz<br>1 GB RAM<br>SME 6 || 7.4 GB, 134,790 files || 7.4 GB, 134,790 files || 100Mbit LAN || no || 35 minutes − |} − − '''Note:''' The last action of a job run is to remove the oldest backup, e.g. if archive scheduled.11 exists and you have set the scheduledKeep property to 12, then it must be deleted. This can take a significantly long time, which increases the total job execution time. − − A affa --rise run on a SME 7.2, 40 GB data, 411.500 files, 2x2.8 Xeon CPU, 1GB RAM, SW-RAID 5 with 4 U320 SCSI drives took 7 minutes including the final reboot. − − ==== Bug report ==== − Affa is listed in the [http://bugs.contribs.org/enter_bug.cgi?product=SME%20Contribs&component=smeserver-affa bugtracker contribs section]. − Please report all bugs, new feature requests and documentation issues there. − − ==== Changelog ==== − <pre> − * Wed Apr 23 2008 Michael Weinberger 1.0.0-2 − Bug fix #4210, command "affa --show-schedule" executes postJobCommand − * Fri Apr 04 2008 Michael Weinberger 1.0.0-1 − Final release − man page updated − * Fri Apr 04 2008 Michael Weinberger 0.10.0-2 − added --all option to --rise − * Mon Mar 10 2008 Michael Weinberger 0.10.0-1 − Increased release number − Added 10 sec timeout in Net::DNS::Resolver->search − * Mon Mar 10 2008 Michael Weinberger 0.9.0-11 − Specfile fix − * Mon Mar 10 2008 Michael Weinberger 0.9.0-10 − Delete locally created watchdog file after remotecopy − Bugfix 4035 − Added default AutoUnmount property to sample script − Fix man page − Do not delete md5sum in --create-backup-file when verify is skipped by user − Set lock in --create-backup-file − * Sun Mar 09 2008 Michael Weinberger 0.9.0-9 − trap signals in --create-backup-file − * Sat Mar 08 2008 Michael Weinberger 0.9.0-8 − Permissions in /usr/lib/affa − * Sat Mar 08 2008 Michael Weinberger 0.9.0-7 − md5sum in --create-backup-file − * Fri Mar 07 2008 Michael Weinberger 0.9.0-6 − Added option --create-backup-file − Using line number as error code in affaErrorExit() − Fixed /etc/profile.d/affa.sh − * Mon Mar 03 2008 Michael Weinberger 0.9.0-5 − delete new style Dovecot's index files dovecot.index* − delete dovecot index files on remote server in --full-restore − * Fri Feb 29 2008 Michael Weinberger 0.9.0-4 − set localhost as default remoteHostName in /etc/e-smith/templates//etc/cron.d/affa/00jobs − * Wed Feb 27 2008 Michael Weinberger 0.9.0-3 − removed %post from spec file − * Sat Feb 02 2008 Michael Weinberger 0.9.0-2 − Bugfix: Report db was not deleted in deleteJob() − don't use -q on ssh commands with Debug=yes − * Fri Feb 1 2008 Shad L.
