1400 | =head1 DESCRIPTION |
1401 | ||
5bf16e38 TL |
1402 | The pve-zsync tool can help you to sync your VMs or directories stored on ZFS |
1403 | between multiple servers. | |
0bc3e510 | 1404 | |
5bf16e38 TL |
1405 | pve-zsync is able to automatically configure CRON jobs, so that a periodic sync |
1406 | will be automatically triggered. | |
1407 | The default sync interval is 15 min, if you want to change this value you can | |
1408 | do this in F</etc/cron.d/pve-zsync>. If you need help to configure CRON tabs, see | |
1409 | man crontab. | |
