Commands:
version Show version program
help Show help program
create Create backup job from scheduler
destroy Remove backup job from scheduler
enable Enable backup job from scheduler
disable Disable backup job from scheduler
status Get list of all backups
clean Clear all backup
reset Remove all snapshots on images specific VM/CT in Ceph
backup Will backup one time
restore Will restore image one time
assemble Assemble a unique image with diff file. (Require eve4ceph-mdti)
Options:
--vmid The ID of the VM/CT, comma separated (es. 100,101,102),
'all-???' for all known guest systems in specific host (es. all-pve1, all-\$(hostname)),
'all' for all known guest systems in cluster,
'storage-???' storage Proxmox VE (pool Ceph)
--label Is usually 'hourly', 'daily', 'weekly', or 'monthly'
--path Path destination backup
--keep Specify the number of differential backups which should will keep, (default: 1)
--renew Specify how many diffs may accumulate, until a full Backup is issued
--renew=10 for keeping 10 Diffs until making a new full export
--renew=7d for making diffs up to 7 days, until making a new full export
--retain Specify how many Backups should be kept, timewise (default: infinite - if unset, nothing is ever deleted)
--retain=30d to keep Backups for 30 days. If the Point in time matches a diff,
it keeps all previous diffs up to the preceding full image to ensure possibility to restore data
--cksum Store checksums for snapshot validation (default: true)
--ckmethod Method used for Checksumming [m5sum, sha1sum, sha224sum, sha384sum, sha512sum] (default: sha1sum)
--qemu-freeze Issue fsfreeze-freeze prio snapshotting and fsfreeze-thaw after snapshot completion (default: true)
--iothreads Specify number of IO threads for exporting (default: 10)
--compress Specify compression method [none,gzip,bzip2,pigz] (default: none)
--compressthreads Specify compression threads for pigz (default: 2)
--script Use specified hook script
E.g. /usr/share/doc/$PROGNAME/examples/script-hook.sh
--syslog Write messages into the system log
--mail Email addresses send log backup, comma separated (es. info@domain.ltd,info1@domain.ltd)
--unprotect-snap Disable protection snapshot, default is protected.
In Proxmox VE 'protected snapshot' cause problem in remove VM/CT see documentation.
--debug Show detail debug
--dry-run Not execute command print only
Report bugs to <support@enterpriseve.com>
