Hi, thank you for your suggestion.
Rsync will copy the whole file new, if the size is different. Since we talk about raw image files of virtual servers, rsync is no option. We need something which will inside of a file just copy the delta's. Something like lvmsync ( which is just working with LVM ). So i am looking for a tool which can do that on a file-base level. -- Mit freundlichen Gruessen / Best regards Oliver Dzombic IP-Interactive mailto:i...@ip-interactive.de Anschrift: IP Interactive UG ( haftungsbeschraenkt ) Zum Sonnenberg 1-3 63571 Gelnhausen HRB 93402 beim Amtsgericht Hanau Geschäftsführung: Oliver Dzombic Steuer Nr.: 35 236 3622 1 UST ID: DE274086107 Am 06.06.2016 um 20:50 schrieb Vasu Kulkarni: > On Mon, Jun 6, 2016 at 11:43 AM, Oliver Dzombic <i...@ip-interactive.de> > wrote: >> Hi, >> >> we will have to copy all data >> >> from: hammer cephfs >> >> to: jewel cephfs >> >> and i would like to keep the resulting downtime low for the underlying >> services. >> >> So does anyone know a good way/tool to make a "pre" copy of the files >> and then just copy the delta's since last copy ? > > are you looking for rsync ? has tons of options > >> >> Thank you ! >> >> >> -- >> Mit freundlichen Gruessen / Best regards >> >> Oliver Dzombic >> IP-Interactive >> >> mailto:i...@ip-interactive.de >> >> Anschrift: >> >> IP Interactive UG ( haftungsbeschraenkt ) >> Zum Sonnenberg 1-3 >> 63571 Gelnhausen >> >> HRB 93402 beim Amtsgericht Hanau >> Geschäftsführung: Oliver Dzombic >> >> Steuer Nr.: 35 236 3622 1 >> UST ID: DE274086107 >> >> _______________________________________________ >> ceph-users mailing list >> ceph-users@lists.ceph.com >> http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
