Using something like VDO for personal storage would be pretty pointless.
Unless, of course, you have a ton of similar virtual machines or other data with high amount of 4 kB block size aligned redundancy.
- globalc 9y agoIf your data directories have much redundancy (so deduplication can help), or are nicely compressable, then VDO can also make sense for home setups. Like companies, you would consider things like "does it make sense for my kind of data", "do I have enough CPU cycles/ram to spend on getting storage down to some degree" and "am I ok with the additional layer, so more complicated setup".
- Arbalest 9y agoimo VDO makes sense where you deal with high speed, low capacity media. I've used BTRFS compression to hold huge disk images in RAM or an SSD while I fully strip/TRIM and repack them (say from RAW to qcow2 or similar). Of course this is usually a case in which I've imported a physical disk image of a 500GB drive, but the actual data on it was only ~50GB or less. Edit: Sorry not the disk image, the temporary overlay for zero blanking. But sometimes smaller disk images for the whole thing. Recently I've also experimentally been holding some older games in RAM on a compressed image.
