1214 | =head1 DESCRIPTION | |
1215 | ||
1216 | This Tool helps you to sync your VM or directory which stored on ZFS between 2 servers. | |
1217 | This tool also has the capability to add jobs to cron so the sync will be automatically done. | |
76b2c677 WL |
1218 | 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. |
1219 | To config cron see man crontab. | |
0bc3e510 WL |
1220 | |
1221 | =head2 PVE ZFS Storage sync Tool | |
1222 | ||
1223 | This Tool can get remote pool on other PVE or send Pool to others ZFS machines | |
1224 | ||
1225 | =head1 EXAMPLES | |
1226 | ||
1227 | add sync job from local VM to remote ZFS Server | |
