1283 | =head1 DESCRIPTION | |
1284 | ||
1285 | This Tool helps you to sync your VM or directory which stored on ZFS between 2 servers. | |
1286 | This tool also has the capability to add jobs to cron so the sync will be automatically done. | |
1287 | The default syncing interval is set to 15 min, if you want to change this value you can do this in /etc/cron.d/pve-zsync. | |
1288 | To config cron see man crontab. | |
1289 | ||
1290 | =head2 PVE ZFS Storage sync Tool | |
1291 | ||
1292 | This Tool can get remote pool on other PVE or send Pool to others ZFS machines | |
1293 | ||
1294 | =head1 EXAMPLES | |
1295 | ||
1296 | add sync job from local VM to remote ZFS Server | |
1297 | pve-zsync create -source=100 -dest=192.168.1.2:zfspool | |
1298 | ||
1299 | =head1 IMPORTANT FILES | |
1300 | ||
1301 | Cron jobs and config are stored at /etc/cron.d/pve-zsync | |
1302 | ||
1303 | The VM config get copied on the destination machine to /var/lib/pve-zsync/ | |
