Hello
back to that thread regarding snapshots, indeed option --skip_dump seems
to work fine, but I cannot find a doc on it, is it undocumented ?
I want to backup openVZ 7 CTs and have read that Legacy vz6 method
should work fine
so from https://openvz.org/Ploop/Backup
I presume I should replace
vzctl snapshot$CTID --id $ID --skip-suspend --skip-config
with
vzctl snapshot $CTID --skip_dump
but does this mean that --skip_dump is the equivalent of --skip-suspend
+ --skip-config ? it allows for a snapshot that keeps the CT running
(no suspend) ?
One more question, based on
https://openvz.org/Ploop/Backup#File-based_backup
I understand that backing up a vzctl snapshot-mount ,
# Take a snapshot without suspending a CT and saving its config
vzctl snapshot$CTID --id $ID --skip-suspend --skip-config
# Mount the snapshot taken
vzctl snapshot-mount$CTID --id $ID --target $MNTDIR
# Perform a backup using your favorite backup tool
# (tar is just an example)
tar cf backup.tar $MNTDIR
will only backup the files modified since the last snapshot, not the
whole CT (latest snapshot + base root.hdd/root.hds ) , I am correct ?
If there is an up2date method to live backup (withoud stopping the CT)
for Vz7 please let me know .
Regards

Hello,
Please try ‘vzctl snapshot $CTID –skip_dump’

Hello,
After upgrade to virtuozzo 7, I have found, that command `prlctl
snapshot` now miss flag `--skip-suspend`.
So, when I try to backup my containers - they are suspended, miss
connections, and act as unavailable for a time.
Do you know, how prevent it and backup whole ploop disk without
down-time? OpenVZ 6 could.
