If there were a ?zfs send? datastream saved someplace, is there a way to verify the integrity of that datastream without doing a ?zfs receive? and occupying all that disk space? I am aware that ?zfs send? is not a backup solution, due to vulnerability of even a single bit error, and lack of granularity, and other reasons. However ... There is an attraction to ?zfs send? as an augmentation to the

hi ! is the "only" compression in rsync zlib compression ? i would like to rsync huge files, which are compressible very good - i wondered how i could use lzop as an compresion option. unfortunately, rsync has no option "--use-compress-program=/path/to/bzip2,lzop,compress,whatever....", like gnu tar has. is this just a missing feature which just has to be done, or would that just be impossible to implement due to "architecture" of rsy...

...fault list of suffixes that will not be compressed is this (several of these are newly added for 3.0.0): gz/zip/z/rpm/deb/iso/bz2/t[gb]z/7z/mp[34]/mov/avi/ogg/jpg/jpeg SUGGESTION Please also add these compresser program extensions to the default list: *.lzo lzop(1) *.rzip rzip(1) *.lzma lzma(1) *.rar rar comressed *.ace ace compressed Archive can also be encrypted for backup purposes, so if possible exclude also these extensions by default: *.tar.gz.gpg *.tar.bz2.gpg *.tar.lzma.gpg *.tar.lzop.gpg -- Configure bugmail: https://bug...

I need to move data from one zpool to another, lock stock and barrel, Being from linux background my instinct was to use rsync. But then I remembered seeing the `export/import options in man zpool.. And I''ve seen mention of them here too, but didn''t pay attention since I''d noticed no need yet. Now I''m wondering if the export/import sub commands might not be

Short of backing up entire disks using dd, I'd like to collect all required information to make sure I can restore partitions, disk information, UUIDs and anything else required in the event of losing a disk. So far I am collecting information from: - fdisk -l - blkid - lsblk - grub2-efi.cfg - grub - fstab Hoping that this would supply me with /all/ information to restore a system - with the

Hi, Since update to 2.6.37 I can''t build openwrt on my btrfs buildroot anymore. I''m not sure if this is related to the other flush-btrfs-1 thread. plenty of diskspace is free: /dev/mapper/cruor-build 97G 68G 27G 73% /opt/build It always hangs when openwrt builds the ext4 image and runs tune2fs on it.

...than libguestfs though. Another thought: why does guestfish need to boot the appliance more than once? Could virsh save/restore or managedsave/stop/start be used? The guestfs appliance seems to be around 80MB saved [*] (perhaps ballooning could help shrink this, or it could be compressed with lz4/lzop).

...t use an existing remote-shell channel... ---------- so, this gives me some hope that this _could_ possible somehow. unfortunately i don`t have a clue, how to write the mentioned wrapper script. i think of something like this: rsync -a -dontConnect2RemoteHostButPipeToSTDOUT ./localdata2sync | lzop -c | netcat remothost 12345 where on remotehosts netcat listens to port 12345 and passes the data to lzop and then to rsync..... otoh, thinking about this, i`m not sure if a pipe could work, because rsync does bidirectional communication with the "remote" end. is something like this...

https://bugzilla.redhat.com/show_bug.cgi?id=847880 https://bugzilla.redhat.com/show_bug.cgi?id=847881 This patch series adds various optional arguments to the tar-in and tar-out commands. Firstly (1/7) an optional "compress" flag is added to select compression. This makes the calls tgz-in/tgz-out/txz-in/txz-out deprecated, and expands the range of compression types available.

If you're planning to rsync it over, tar it up, and delete the directory tree, you should just tar|gzip it on the work system and catch that in a file on the other end.
